The US has announced it will send controversial weapons to Ukraine as part of more than $1billion in military and humanitarian aid.
Russia condemned the move to equip US Abrams tanks with shells strong enough to pierce conventional tank armour.
Overnight, suspected Ukrainian drone attacks were reported on the Russian city of Rostov-on-Don and near Moscow.
The announcement of a new security package for Ukraine came during top US diplomat Antony Blinken’s visit to Kyiv, prompting an angry Russian response.
The weapons are due to be delivered to Ukraine later this year.
