The New Arab concludes its live coverage of the latest from Russia’s invasion of Ukraine.
Here's a recap of the latest major developments from Sunday:
Putin puts nuclear forces on alert
NATO slams Russian President Vladimir Putin for putting his nuclear forces on alert, saying it was dangerous and "irresponsible", with the White House claiming he was again "manufacturing threats that don't exist in order to justify further aggression".
Russians driven from Kharkiv
Ukraine claims to have expelled Russian troops from its second city Kharkiv in the east of the country after Russian armoured vehicles got through its defences.
Kyiv holds out
Ukraine says it is holding the line around the capital Kyiv but was fighting Russian "sabotage groups" that had infiltrated the city.
Talks near Chernobyl
Ukraine agrees to hold talks with Russia at its border with Belarus - near the Chernobyl exclusion zone - after a call between President Volodymyr Zelensky and Belarus leader Alexander Lukashenko.
Kremlin's big push
The talks come as Russia orders an advance "from all directions". It claims to have besieged the southern cities of Kherson close to Crimea and Berdyansk on the Sea of Azov.
Russians 'lack momentum'
But Washington says the invading forces have lost "momentum over the last 24 hours" after meeting stiff resistance and still have not gained air superiority.
Nearly 400,000 refugees
The UN's refugee agency says tens of thousands are fleeing the fighting, with most crossing into Poland as the total tally reaches 400,000. Others are seeking shelter in Hungary, Romania, Moldova and Slovakia.
