Good evening. Volodymyr Zelensky, the Ukrainian president, has warned Russia that peace talks would end if Kremlin forces “eliminate” the remaining Ukrainian soldiers in Mariupol.

It comes after more than 1,000 troops defending the besieged city were forced to surrender when they ran out of ammunition and vital supplies.

Elsewhere, Russia has resumed bombarding Kyiv with long-range missiles in revenge for Ukrainian forces sinking its Black Sea flagship, the Moskva.

Here are the latest developments in the conflict.

1. ‘Elimination’ of last Mariupol troops would end peace talks

The elimination of the last Ukrainian troops trapped in the besieged port of Mariupol would put an end to talks with Moscow, Mr Zelensky said on Saturday, in an interview with the Ukrainska Pravda news website.

“That will be an impasse as we don’t negotiate neither our territories nor our people,” he said.

The strategic port of Mariupol has been among the hardest hit after Russia invaded Ukraine on February 24.

2. Russia launches fresh missile attacks on Kyiv

Russia stepped up airstrikes on Kyiv on Saturday, killing at least one person at a tank factory a day after Moscow warned it would renew attacks following two weeks of relative calm in the Ukrainian capital.

Vitali Klitschko, the Kyiv mayor, said at least one person was killed and several wounded in the attack.

Smoke rose from the Darnyrsky district in the south-east of the capital after what Moscow said were “high-precision long-range” strikes on the armaments plant.

“Our forces are doing everything possible to protect us, but the enemy is insidious and ruthless,” Mr Klitschko said.

“It’s no secret that a Russian general recently said they were ready for missile attacks on the capital of Ukraine. And, as we see, they are carrying out such shelling.”

3. ‘Hundreds dead’ after Ukraine sinks Russia’s flagship

Hundreds of sailors are believed to have died aboard the Russian flagship the Moskva, after it was sunk by Ukrainian missiles. Reports suggested that just a few dozen of the 510-strong crew were able to be rescued.

It took the Russian military almost a day to admit the embarrassing loss of the pride of its Black Sea fleet, after it was hit in the early hours of Thursday. Initially, the Kremlin insisted it had caught fire after an explosion and was being towed back to land.

But the US has since confirmed that the warship was hit by two Ukrainian strikes, believed to be Neptune anti-ship missiles.
