At least half of the population of Kyiv has no electricity as a result of emergency shutdowns following the Russian missile strikes, according to the city's mayor.

"Due to a massive missile attack...the energy industry started emergency power shutdowns throughout Ukraine," Vitali Klitschko said on Telegram., external

"In the capital, at least half of the customers are cut off electricity," he added, stating that the shutdowns were a "necessary step to balance the power system and avoid equipment accidents".

As well as special emergency outages in Kyiv, the national grid operator, Ukrenergo, also introduced emergency power outages for "all categories of consumers" in northern and central regions where the worst damage to power lines has been seen.

Let's go back to the G20 summit now, where it appears Russian Foreign Minister Sergei Lavrov has not left Bali after all, despite earlier reports.

It had been suggested that Lavrov had departed the summit hours after criticising Western nations for what he described as the "politicisation" of the G20 declaration.

But according to a spokesman for the Indonesian ministry of foreign affairs, Russia's representative at the summit is due to leave tonight.

Also leaving tonight are the leaders of South Korea, the UAE and Cambodia, Teuku Faizasyah says.

These are the first Russian missile strikes on Ukraine's cities since Kyiv's forces liberated the key southern port city of Kherson on Friday.

The recapture of Kherson is seen by Ukrainians as a major victory - like the retreat of Russian troops from the Kyiv suburbs in March - and a humiliation for the Kremlin.

Some 30,000 Russian troops withdrew to the eastern bank of the Dnipro, and at the weekend there were celebrations in Kherson. The city had been under Russian occupation since early March.

But before today Russia had already fired hundreds of missiles at Ukrainian cities, hitting residential blocks, power stations and many other civilian installations. Many were cruise missiles fired from Russian bombers or ships positioned outside Ukrainian territory.

Ukraine says its air defences have shot down many Russian missiles during these strikes.

Russia claims the Kherson region and three other occupied Ukrainian regions to be part of Russia, as well as Crimea, which Russia annexed in 2014. The claim - following hastily organised local "referendums" - is rejected internationally.

Videos and images are now emerging showing the aftermath of a missile strike on a residential building in Ukraine's capital Kyiv.

Russian missiles struck two residential buildings in the city, according to Mayor Vitaliy Klitschko.

A video shared by the president’s office shows a block of flats on fire. Orange flames are seen billowing from several apartments.

Firefighters are working to extinguish the blaze, with no immediate information on casualties.

We're beginning to get a picture of the wave of Rusian missile attacks across Ukraine.

Blasts have also been heard in the north-eastern city of Kharkiv, according to Interfax Ukraine news agency.

Kharkiv's mayor, Igor Terekhov, said there was a "missile attack" on the city and there is no information on casualties at the moment.

He said due to damage, there are problems with the power supply in the city which has stopped electric transport and the metro."Power engineers and public utilities are doing everything to normalise the life of Kharkiv as soon as possible," he said on Telegram.

Explosions are also reported in the northern city of Zhytomyr, according to Ukrainian broadcaster Suspilne.

The head of President Volodymyr Zelensky’s office has tweeted that this “massive” missile strike is Russia’s “answer” to the speech by Ukraine's president to the G20 summit.

“Does anybody think the Kremlin seriously wants peace? The Kremlin wants obedience. But in the end the terrorists always lose,” Andriy Yermak tweeted., external

At the G20, Zelensky urged world leaders, via video link, to end “the Russian destructive war”, and called it the G19 – that is, the G20 minus Russia.

Explosions have been heard in the western city of Lviv, the city's mayor Andriy Sadovy has said.

"Part of the city is without electricity," he said on Telegram.

Sadovy advised everyone to stay in shelters.

We're getting more details now on the strikes on Ukraine, with an adviser to the defence minister estimating that Russia has lunched about 70 missiles on the country this afternoon.

“Right now as we speak I have seen reports that about 70 ballistic missiles have been launched on Ukraine," Yuriy Sak says.

Here's what we know so far about new Russian missile strikes on Kyiv and other Ukrainian cities:

• Russian missiles have hit two residential buildings in Kyiv, Mayor Vitaliy Klitschko reports - he says several missiles were also shot down by the city's air defence; emergency services are at the scene
• Explosions were also reported in Khmelnytskyy and Kryvyi Rih, in the south, and Chernihiv in the north
• Air raid alerts have been sounded right across Ukraine
• The governor of Krivyi Rih says cruise missiles were fired from a Russian Tu-95 bomber over southern Russia
• The BBC can't independently verify exactly where and what has been struck at this stage

As we await more information on what's happened in Kyiv, here is the first image we've had from the scene of one of the missile strikes.

Russia has launched an attack on the Ukrainian capital Kyiv, with explosions heard and smoke seen rising.

Two residential buildings in the central Pechersk district were among those hit, according to the city's mayor Vitali Klitschko.

World leaders are currently at a meeting of the G20 in Indonesia where they have condemned the war on Ukraine.

Several Russian missiles have been successfully shot down and rescue teams are in place, Klitschko said.

An air raid alert has also been declared in Kyiv.

Wednesday is the last day of the G20 in Bali - meaning we will get the group's final declaration on the outcomes and resolutions of this year's summit.

UK PM Rishi Sunak is expected to spend some time meeting several world leaders, including US President Joe Biden, before leaving Indonesia at around lunchtime UK time. Other bilateral meetings and press conferences are also expected to take place on the sidelines of the main summit.

And we've just heard that Russian Foreign Minister Sergei Lavrov has left Bali and is on his way back to Russia, according to Russian news agency Tass.

The G20 summit officially ends tomorrow, after the leaders' communique is issued.

Kyiv has been attacked by missiles, the city's mayor says, as world leaders condemn Russia's invasion of Ukraine.

Against the backdrop of the G20, other international organisations are working to come to shared resolutions on the global affairs of the day.

Yesterday, the UN General Assembly passed a resolution saying Russia should face the consequences of its actions in Ukraine, including paying reparations.

It also recommends that member states, in collaboration with Ukraine, create an international register to record evidence and claims against Russia.

General Assembly resolutions may carry symbolic weight, but they do not have the power to enforce compliance. Indeed, Russian Ambassador to the UN Vassily Nebenzia labelled the resolution "legally null and void", and accused the West of "trying to draw out and worsen the conflict".

Kyiv's UN Ambassador Sergiy Kyslytsya told the assembly that in addition to needing finance to rebuild infrastructure, recovery "will never be complete without a sense of justice for the victims of the Russian war", adding: "It is time to hold Russia accountable."

The resolution was supported by 94 out of 193 member states, while 14 - including Russia, China and Iran - voted against it. The remaining countries all abstained.

Oleksandr Vasiuk, a top Ukrainian official responsible for overseeing dialogue with the US, has shared his reaction to concerns at the G20 about the global impact of the ongoing war.

"President Volodymyr Zelensky presented 10 concrete and fair steps that will help bring peace back to Ukraine - to ensure food and energy security for Europe and the whole world," Vasiuk told the BBC.

"It is worth noting that the president spoke at the summit immediately after returning from de-occupied Kherson - the only regional centre that Russian troops managed to capture after 24 February. This day was a turning point in the war and it shows that other cities and territories will soon be liberated", he added.

The Ukraine war has cast a long shadow over the G20 summit, and all eyes are on what its final communique - or declaration - will have to say about Russia’s invasion.

Russia is a member of the group and it remains an open, and awkward, question as to whether the statement will have Moscow’s participation.

The other big question is how far it might get watered down. Versions of a draft statement leaked to some media outlets suggest that it could say “most” G20 countries strongly condemn the war in Ukraine.

But the declaration – to be formally adopted by leaders on Wednesday – is likely to be negotiated up to the very last minute.

Russia’s Foreign Minister Sergei Lavrov has already hit back, saying that Western countries are trying to "politicise" the declaration by pushing a line condemning the invasion on behalf of all countries, including Russia.

But world leaders have also made it very clear they have little patience left. At the opening of the summit, Indonesian president and summit host Joko Widodo insisted the Russian war must end, while UK PM Rishi Sunak told Lavrov Russia must “get out” of Ukraine.

Meanwhile, all eyes are also on China and how it could influence Russia. But so far, despite lobbying efforts from the US and France, Xi Jinping has given little public indication that he plans to do more to push President Putin to end the war.

He has repeated China’s calls for peace at this summit but at the same time emphasised that there is "no simple solution to a complex problem".

Earlier this week, senior US officials told reporters they believed China was “surprised and embarrassed” by Russia. But in public at least, China is making it clear it will not lean any further on its close ally.

If you're wondering what the fuss is all about, here is a recap.

The G20, or Group of Twenty, is a club of countries which meets to discuss plans for the global economy.

Between them, G20 countries account for 85% of the world's economic output and 75% of world trade, external. They contain two-thirds of the global population.

The members are the European Union and 19 nations - Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea, Turkey, the UK and the US. Spain is always invited as a guest.

There is often a risk of political tensions risk overshadowing the summit. This year, Ukraine's foreign ministry asked for Russia to be expelled from the G20, external because of its invasion of Ukraine.

On other occasions, the leaders' group photograph used as an opportunity to sell whatever agreements the leaders have signed has also been examined for signs of tension between heads of state.

In 2018, following the killing of journalist Jamal Khashoggi at the Saudi consulate in Istanbul, Prince Mohammed bin Salman was largely ignored at the leaders' summit and made to stand at the far end of the group.

Ukrainians are reacting to President Volodymyr Zelensky’s speech to the G20 summit and unsurprisingly they are backing his statements.

The line from officials and Ukrainians themselves is that Russian troops need to pull out from the whole country for there to be negotiations.

Oleksiy Goncharenko, a Ukrainian MP told the BBC: "Ukraine wants peace, and we want peace more than any other nation in the world today because we’re suffering from this awful war."

He added there would need to be a lasting peace so that the world did not "become like a wild jungle with a predator hunting for peaceful nations".

Ukraine can still rely on the support of Western countries, the US and UK in particular. But the G20 summit has also highlighted the pressure from other nations, in particular India and Indonesia, for negotiations to happen sooner rather than later.

The prime minister goes on to discuss the UK's free trade deal with Australia, which was yesterday described by former environment secretary George Eustice as a failure.

Eustice argued it gave away "too much" after the then trade secretary Liz Truss "shattered" the UK's negotiation.

Rishi Sunak previously said in August, the deal - the first post-Brexit deal negotiated from scratch - was one-sided and bad for British farmers.

Asked why he plans to press ahead with the agreement now, the PM tells the BBC he wants to make sure "we don't sacrifice quality for speed when it comes to trade deals".

"I think with trade deals there's always give and take and with the Australia deal in particular, some of the highlights are that it will be easier for people to travel and work in Australia, it will support something like three million British jobs where their jobs are connected to exporting to Australia and it will make many Australian goods cheaper," he says.

"There are many positives from this deal but it is right going forward that we don't sacrifice quality for speed. I want to take the time to get trade deals right, right for Britain.

"I think that's the right approach and that's what we will do going forward."
