Hours after the Russian missiles struck in Dnipro, the wreckage of a shoe factory was still burning.

There were clouds of acrid smoke rising from the ruins as firefighters continued dousing the flames with water.

The factory’s director was wandering, dazed, through the rubble.

When I asked about the strike, she pointed to the spot where the firm’s security guard had been killed. A man told me his name had been Vitya, and he was retired: night shifts at the factory gates were a way of topping up his pension.

Round the back of the shattered building, firemen were passing out bright-coloured rolls of fabric, forming a human chain to salvage anything useful from the ruins.

Locals and factory staff were sorting through the mangled mess in the yard, trying to clean up. Their task seemed impossible.

Before this, Dnipro had seemed relatively safe. The air raid sirens wailed every day, but they were detecting missiles or planes flying over the city, not at it.

All that’s changed now. People seem dazed, distressed. Disbelieving.

US President Joe Biden says the US will revoke Russia's "permanent normal trade relations" status to punish Moscow over its invasion of Ukraine.

The change, which he says is being taken together with moves by US allies, will pave the way for the US to impose tariffs on a wide range of Russian goods, heightening pressure on an economy on the brink of deep recession.

He says the totality of sanctions and export controls are "crushing" the Russian economy.

"We’ll continue to squeeze Putin," he says, adding: "He is the aggressor, he must pay the price."

He also says Russia will "pay a severe price" if it uses chemical weapons.

President Zelensky says Ukraine has reached a turning point and is "on the way to victory".

Speaking in a televised address earlier, he says: "It’s not possible to say how many days it will take to liberate our Ukrainian land.

"But it is possible to say that we will do that because we have achieved already the turning point strategically – we are on the way to our victory."

This is a "patriotic war" against a "strong and obstinate enemy which doesn’t pay attention to thousands of their own soldiers dead", he says.

Referencing reports of Russia utilising mercenaries in their invasion, he says: "Artillery, bombs, missiles – now there’s Syrian mercenaries who do not differentiate who speaks which language here... those mercenaries are just simply built to kill, in a land alien to them."

He repeated his call for the EU to do more for Ukraine as Russia widens its attack, targeting fresh cities overnight.

"At night, the invaders were bombing a shoe factory, a block of flats and a nursery in Dnipro. What for?

"If this continues, that the price of the sanctions for Russia is not enough... we are expecting new sanctions – Russia should pay for this horror war."

Ukrainian officials have accused Russia of bombing Belarusian settlements from Kyiv's airspace on Friday afternoon.

Ukraine's general staff said that border guards had received information that Russian aircraft had taken off from an airfield in Belarus, crossed into Ukrainian air space and then fired at the southern village of Kopani.

The BBC has not been able to independently verify that an attack has been prepared or has taken place.

In a message posted to Facebook Ukraine's defence minister Oleksiy Reznikov warned Belarusian citizens that Russian forces were preparing the assault.

"According to their criminal intentions, Russian aviation is preparing to hit a series of settlements on the territory of the Republic of Belarus, situated close to the Ukraine-Belarus border. Specifically, they plan to hit Kopani," Reznikov said.

"The purpose of the provocation is to force the current leadership of Belarus into war against Ukraine. Moscow is trying to bind you with blood," he added.

"I guarantee that the Ukrainian army has not planned, does not plan and will not plan any aggressive actions against Belarus."

It comes as Ukraine's Deputy Interior Minister Yevheniy Yenin said the Belarusian government has "been doing everything possible to avoid joining this war".

Western officials have confirmed that a third Russian major general has been killed in Ukraine, adding that he was from Russia's eastern military district.

Officials didn't name the general, but earlier Ukraine's military said Maj Gen Andrei Kolesnikov, commander of the 29th army of Russia's eastern district, had been killed.

Analysts have previously said that the presence of high-ranking military figures on or near the battlefield could be a sign that Russia's operations are not going to plan.

Some Ukrainian refugees are applying for visas to join family in the UK.

The British government, which has been criticised for imposing a long, complicated process, has now announced that applications can be made online from next week.

Our correspondent Mark Lowen has been speaking to Lena Kamolikova at the UK visa centre in Rzeszow, eastern Poland - who travelled from London to help her Ukrainian mother Raisa.

We reported earlier about the air strikes that have hit the city of Dnipro in central Ukraine. Among the buildings hit by missiles were a shoe factory and an apartment block.

Our correspondent on the ground, Sarah Rainsford, has sent these pictures.

"This is what Russian missiles do," she said. "This shoe factory is in the middle of a residential area in Dnipro. The security guard and his dog were killed.

"Many flats have been badly damaged. A woman was woken by her son screaming in terror. And all these Russian speakers are now furious - at Russia."

Russia has now confirmed that it will restrict access to Instagram.

It comes after the social media site's parent company, Meta, changed its rules in some countries to allow the expression of violent sentiment towards Russian forces, but not towards Russian civilians.

Russia's media regulator says, external Instagram is distributing material calling for violent acts to be carried out against Russian citizens.

It isn't clear yet whether Instagram will be completely blocked or limited in some other way.

Access to Facebook, also owned by Meta, and Twitter has already been restricted.

If you're just joining us, here are all the latest developments from Ukraine as the Russian invasion enters its 16th day:

• Ukrainian officials say they have killed Maj-Gen Andrei Kolesnikov, a senior Russian officer and commander of the 29th Army of the eastern district. The BBC cannot verify the claim and Moscow has yet to comment on the reports
• Regulators in Russia have applied to designate Meta as an "extremist organisation" after the company confirmed it will change its policies to allow for calls for violence against Russian forces
• President Vladimir Putin has told Belarusian leader Alexander Lukashenko that there have been some "positive" developments in ongoing negotiations with Ukrainian leaders
• But he also gave the go-ahead for volunteers from the Middle East to fight for Russia in Ukraine
• Elsewhere, the UK has sanctioned 386 members of the Russian state Duma who support Putin's invasion of Ukraine. The sanctions will ban those listed from travelling to the UK, accessing assets held in the country and doing business in its jurisdiction
• Meanwhile, the UK's veterans minister has urged ex-servicemen "not to engage" in the conflict following reports of several British military personnel travelling to Ukraine to Ukraine's forces
• And the EU has presented a plan to phase out the EU's dependence on Russian fossil fuels by 2027

The funerals are happening across Ukraine every day. Different families grieve, but the anguish of the graveside farewells is universal.

Here in Lviv trains carrying the coffins of the dead are met by honour guards of fellow soldiers. The ceremony of grief unfolds over several days. Funerals begin with a mass and the reading of eulogies to the dead at the garrison church of Saints Peter and Paul in the city centre. It is a church that has a long association with the military.

The three soldiers buried today were killed fighting in Kherson, southern Ukraine, where Russian forces have been trying to advance.

The dead were Sgt Dmytro Kabakov, aged 59, Senior Soldier Andriy Stefanyshyn, aged 40 and Lt Taras Didukh, aged 25.

Midway through the funeral air-raid alarms sounded. But the mourners did not stir.

All attention, all emotion was focused on the three coffins, draped in the Ukranian flag, that lay before the altar.

Ukraine's nuclear power regulator has said that power has not yet been restored to the Chernobyl nuclear plant.

The statement contradicts claims by Russia's energy ministry, which had said that power was restored to the plant by Belarusian specialists on Thursday.

Ukraine has warned of potential radiation leaks if power cables, which were damaged during intense fighting between Kyiv's and Moscow's forces, are not repaired.

"Attempts to restore the external power supply to the site are in progress," the State Nuclear Regulatory Inspectorate of Ukraine said in a statement.

We've got through lots of your questions in the last hour or so. We hope it helped make sense of a complex and rapidly changing situation. Thank you for getting in touch, and thanks also of course to Lyse Doucet in Kyiv and Jenny Hill in Moscow.

A high-ranking Russian officer has been killed by Ukrainian forces, according to the Ukrainian military, external.

Maj-Gen Andrei Kolesnikov was the commander of the 29th army of Russia's eastern military district, according to Anton Gerashchenko, an adviser to Ukraine's interior minister.

The details of his death are unknown and there has been no comment from the Russian side.

At least two other officers of the same rank have reportedly been killed since the war began two weeks ago.

Western officials have previously said the fact that such senior Russian officers have been exposing themselves to danger may be a sign of frustration that their advances have stalled.

What is Belarus' involvement in the conflict?published at 13:59 Greenwich Mean Time 11 March 2022

And our last question comes from Steve Simmons-Jacobs in Romsey who asks: "Can you tell us what Belarus is doing in this conflict? Is any of their army actually taking part?"

Neighbouring Belarus became a staging ground for Russian troops and heavy weaponry in the weeks leading up the invasion (even though it was described as military exercises) and then it became a launching pad for Russia to move into Ukraine, and for Russian missile strikes across the border.

So far, the US says it sees no evidence that Belarussian forces have become directly involved.

It has also hosted talks between Russian and Ukrainian negotiating teams close to the border.

In 2020, Russian forces helped Belarus' leader, Alexander Lukashenko, survive an unprecedented uprising against his rule. Russian President Vladimir Putin expects him to return the favour.

However, although it was announced before the invasion that Belarus could join the fight, Lukanshenko recently said he wouldn't.

The Ukrainian President Volodymyr Zelensky also made a direct appeal to Belarus last month, saying "Be Belarus, not Russia."

How might Nato respond if Russia takes all of Ukraine?published at 13:54 Greenwich Mean Time 11 March 2022

Jeff Moono in Lusaka asks: "If Russia takes control of the whole of Ukraine, what would the response be from Nato and the USA?"

That’s the nightmare scenario for Nato, which has bolstered troop numbers in neighbouring countries but which, for the reasons outlined above, does not want to be drawn into a war with Russia.

There’s speculation that, before that eventuality arose, Kyiv might be persuaded to do a deal with Moscow – in other words, hand over some of its territory in return for a cessation of hostilities.

However, the problem with that scenario is, firstly, that Kyiv doesn’t want to give ground, and secondly, there’s also a fear that such an outcome might embolden Putin.

Nevertheless, right now most analysts assume that Russia would struggle to hold Ukraine in the long term.

Are there enough blood supplies?published at 13:49 Greenwich Mean Time 11 March 2022

"As the fighting continues and more people and soldiers will suffer horrific injuries from the bombing, will they have enough blood supplies?" asks Linda Potter on email.

"Should people be donating their blood?"

I remember when this invasion started more than two weeks ago call went out for blood donations.

Ukrainians are signing up to fight, and to donate blood – wherever and whenever they can.

But, like you, they must be asking if they have enough.

"If Russia is committing war crimes, why is there not a tribunal investigating it?" asks Elaine Craig.

The chief prosecutor of the International Criminal Court in The Hague has said that he’s collecting evidence of alleged war crimes, crimes against humanity and genocide.

"Will the potential for a Nato engagement increase if dirty bombs or chemical weapons are used?" asks Gordon Mains in Glasgow.

This question must be on the minds of Nato members. But they are very careful and cautious about not being drawn into this war beyond the supply of military weapons and ammunition.

Nato’s principle of “collective defence,” enshrined in their Article Five, is “an attack against one ally is considered as an attack against all allies”. It is now trying to defend “every inch” of Nato territory but there’s a laser focus on any threats which cross the border.

They know this threat exists – although Russia says it has no plans to invade other countries.

Kate Russell in Glasgow asks: "After seeing all the trains leaving cities under attack fully packed with people, why aren’t more being sent in to rescue the fleeing people?"

The trains are running, many on time, even in this war. But in some places, including Irpin just west of Kyiv, the tracks were attacked so that station is now not in use.

I noticed on my last trip to the wonderful 19th Century train station in Kyiv that the platforms for trains heading west were not as crowded, although the trains pulling out are certainly still full.

What's the latest on sanctions?published at 13:27 Greenwich Mean Time 11 March 2022

We've heard a lot about the sanctions imposed on Russia in recent days. Alfred Pons from Albuquerque in the US asks: "When do all of the sanctions go into effect?"

Many have already taken effect but others are pending.

The UK has just announced sanctions on 386 members of the Duma, the lower house of the Russian parliament, who support the invasion of Ukraine. This brings the total number of Duma members sanctioned by the UK to 400.

And the EU says it remains ready to impose more sanctions.
