A company that produces Atomik - a vodka made in Chernobyl's exclusion zone - is releasing two more premium drinks and donating profits to Ukraine's refugees.

The move comes as Russian troops occupy the land where the fruit is grown and harvested to make the drinks.

Scientists who set up the Atomik project have studied crops grown in the Chernobyl exclusion zone for 30 years.

Their work has enabled people living on contaminated land to distil slightly radioactive fruit down to a spirit that is no more radioactive than any other.

The UK's Ministry of Defence (MoD) has given an update on the latest fighting in Ukraine, external, saying that:

• Russian forces continue to strike targets across Ukraine, including targeting many densely populated civilian areas
• Russia continues to rely on munitions launched from within Russian airspace in order to reduce their aircrafts' exposure to Ukrainian air defences

• The US has reported these weapons have a failure rate of up to 60%, which is forcing Russia to switch to less sophisticated missiles

The Armed Forces of Ukraine have also posted an update on Facebook, external, with these key points:

• Russia has continued to attack civilian and military infrastructure in the besieged south-eastern city Mariupol
• It has also continued to target the Ukrainian capital Kyiv, firing on suburban areas and directly into the city

• Armed forces in neighbouring country Belarus, which is an ally of Russia, have been conducting training activities in Brest, Minsk and Grodno regions

Russia does appear to have lowered its ambitions, claiming it has "generally accomplished" the aims of the invasion's first phase, which it defined as considerably reducing Ukraine's combat potential.

The main goal, we are now told, is the "liberation of Donbas" - broadly referring to Ukraine's eastern regions of Luhansk and Donetsk. More than a third of this area was already seized by Russian-backed separatists in a war that began in 2014.

Russia wants all of it, as spelled out by President Putin when he recognised the whole area as belonging to two Russian puppet statelets in the lead-up to the invasion. It will also try to control Ukrainian territories along the south coast, east from Crimea to the Russian border.

And his broader demand is still about ensuring Ukraine's future neutrality.

Thousands from Prague's Russian community marched through the city waving flags and holding up signs denouncing Russia's invasion of Ukraine.

Several activists threw red paint, symbolising the blood of those killed in the war so far, on the stairs of the Russian embassy in Prague.

Carrying square signs that said "Putin, go to hell" and "Stop Putin, Stop war", protesters walked through the centre of the Czech capital.

The US State Department has said that it will provide Ukraine with $100 million in civilian security assistance "to provide essential border security, sustain civil law enforcement functions, and safeguard critical governmental infrastructure".

This comes as Russian strikes on Ukraine continue - on Saturday, the western city of Lviv, which has largely been spared so far, came under heavy rocket fire.

US President Biden is visiting Poland, whose border is just 70km from Lviv.

On Saturday the western Ukrainian city of Lviv came under heavy rocket fire, one of several targets in the west to be struck despite Russia saying it would focus on the east.

Lviv has so far escaped the heavy bombardment seen by other cities, and has become a hub for those fleeing the fighting.

Lviv's Mayor, Andriy Sadovy, said with US President Joe Biden visiting Poland, the timing was clear.

"With today's strikes, the aggressors want to say hello to President Biden who is currently in Poland," he said.

"Lviv is only 70 km from the Polish border and I think the world needs to understand that the threat is very very serious."

Russian general Lt Gen Yakov Rezantsev has been killed in a strike near the southern city of Kherson, according to Ukraine's defence ministry

Rezantsev was the commander of Russia's 49th combined army.

A western official said he was the seventh general to die in Ukraine, and the second lieutenant general - the highest rank officer reportedly killed.

Some reaction to Biden's speech now from the Polish Ministry of Foreign Affairs.

Biden spoke from Poland's capital Warsaw where he said Putin "cannot remain in power".

"The president of the most powerful country in the world came to Warsaw and spoke very plainly about the Russian aggression", spokeswoman Lukasz Jasina told the BBC.

"[Biden] said to Russians that there is always time to change a dictator. It was a very moving and deep experience."

"Putin cannot be accepted back into our world society; he cannot be heard, he is not a partner we trust", Lukasz says.

Poland shares a border with Ukraine and has played a key role responding to Russia's invasion, taking in more than two million refugees.

Russian oligarchs, banks and businesses could have sanctions against them lifted if Russia's President Vladimir Putin ends his invasion of Ukraine and commits to "no further aggression", UK Foreign Secretary Liz Truss has said.

She told the Sunday Telegraph newspaper that the threat of "snapback sanctions" would be retained if the Russian president did attack again.

The foreign secretary also said that a "negotiations unit" had been established in the UK Foreign Office to aid possible peace talks.

Russia has shown signs of possibly scaling back its ambitions in Ukraine, with a senior military official saying on Friday that its efforts were now turning to the eastern Donbas region. However the Western city of Lviv, which until now has largely stayed unscathed, came under heavy rocket fire on Saturday.

Residents of several apartment blocks in the centre of Kyiv were treated to an impromptu concert by a band made up of Ukrainian soldiers.

The band performed a few Ukrainian pop music classics as well as the national anthem.

All entertainment venues have been closed since the start of the Russian invasion and live music has become a rare treat.

Musicians in Ukraine's second city of Kharkiv have performed an emotional concert in a metro station, which is being used as a makeshift shelter.

Kharkiv has been the target of intense Russian bombardment for weeks, leaving residents to take shelter in bunkers and metro stations.

The concert marked the opening day of the Kharkiv Music Festival.

Biden's speech: "For God's sake, this man cannot remain in power", US President Joe Biden said of his Russian counterpart Vladimir Putin during a speech in Poland's capital Warsaw. The White House later said Biden wasn't calling for regime change, but making the point Putin can't be allowed to exercise power over neighbours. The Kremlin said it wasn't for Biden to decide who governs Russia

Lviv rocket fire: Powerful explosions have been heard in Lviv, with thick black smoke seen rising over the outskirts of the city. Lviv is in the west of Ukraine not far from the Polish border and the city's mayor has said he thinks the Russian air strikes were intended to send a message to Biden. Lviv has become something of a safe haven for Ukrainians escaping the conflict

Zelensky's speech: Ukrainian President Volodymr Zelensky has demanded the West steps up military supplies to his country. He said it wasn't only Ukraine at risk and just 1% of Nato's tanks and aircraft are needed to help his forces fight Russia

Chernobyl fighting: There are concerns over the welfare of staff at Chernobyl's power plant as there hasn't been any staff rotation for nearly a week. The International Atomic Energy Agency (IAEA) said it was worried about the pressures faced by Ukrainian staff at nuclear sites seized by Russia
