Peace talks continue
Peace talks between Russia and Ukraine were set to continue via videoconference on Monday, local time, Russian chief negotiator Vladimir Medinsky said.
Russia said on Sunday that talks had not progressed enough for a leaders' meeting.
Moscow said its positions on the status of Crimea (which Russia annexed from Ukraine in 2014) and two Russian-backed rebel regions in the eastern Donbas (which President Vladimir Putin recognised as independent in February) remained unchanged.
The two sides have held periodic talks since Russia launched its invasion, but there has been no breakthrough and they remain far apart on the question of territory.
Russia has depicted its drawdown of forces near Kyiv as a goodwill gesture in peace talks.
Ukraine and its allies said Russia was forced to shift its focus to east Ukraine after suffering heavy losses.

Satellite images show mass grave in Bucha
Ukraine has accused Russian forces of carrying out a "massacre" in the town of Bucha, near the capital Kyiv.
Ukraine authorities found 410 bodies in towns near Kyiv as part of an investigation into possible war crimes by Russia, the country's top prosecutor said.
US Secretary of State Antony Blinken described images of dead bodies as "a punch in the gut".
A satellite image from Bucha showed a trench around 14 metres in length dug into the grounds of a church where a mass grave had been identified, US company Maxar Technologies said.
The image, captured on March 31, followed previous imagery from March 10 that showed signs of excavation on the grounds of the Church of St Andrew Pyervozvannoho All Saints.
Russia's Defence Ministry denied allegations its forces were responsible for the deaths of civilians, and said Ukraine had staged a performance for the Western media.
Moscow requested the United Nations Security Council convene to discuss what Russia called a "provocation by Ukrainian radicals" in Bucha.

Promising luxury, London lured Russian billionaires to the UK. Then the city got 'blinded by the bling'
Nearly three decades ago, the UK started offering a "golden visa" to the world's ultra-rich.
Thousands of Russians bought lavish homes and sent their children to the best boarding schools.
But critics say it turned London into a haven for their riches.
Europe bureau chief Steve Cannane takes a look at this issue, reporting from London.

Ukraine accuses Russia of massacre in Bucha as 410 bodies found

After Russia withdrew from some areas around Kyiv, the mayor in Bucha, a liberated town 37 kilometres north-west of the capital, said that 300 residents had been killed by Russian forces while Chechen fighters controlled the area.
Russia has denied the allegations that its soldiers killed civilians in Bucha.

Inside the remains of the bombed Mariupol theatre, in Ukraine's Donbas region
The badly damaged interior of a theatre in Mariupol bears testimony to the scale of Russian attacks on the Ukrainian port city.
Ukrainian authorities said about 1,000 people had sought shelter in the theatre as Russian forces destroyed the city.
On March 16, an attack was carried out on the theatre, despite the fact the word 'children' had been written in enormous letters, in Russian, in two places on the ground outside to indicate young families were sheltering there.

Eastern Africa suffering as a result of the Ukraine-Russia war
Speaking to ABC News Breakfast, Michael Dunford — the World Food Programme's regional director for Eastern Africa — said the war in Ukraine was having a major impact on the region.
We estimate that almost 90 per cent of all of the wheat that this region consumes is imported.
Much of that is coming from both Ukraine and Russia.
In addition to that, these countries are highly reliant on the fertiliser which originates again from Russia and Belarus.
[In] Ethiopia, 90 per cent of all of their fertiliser [is] coming from those two countries.
So, we're having the combined impact of increased costs, a lack of availability of key items, and this is taking the region to the brink of hunger.
