The US on Monday pledged to ensure air-defence systems for Ukraine, after a large-scale air attack on Kyiv the same day, killing at least 14.

After the attack, a telephone conversation was held between the presidents of Ukraine and the United States of America, Volodymyr Zelensky and Joe Biden. 

Washington said that Biden had condemned the Russian missile strikes and expressed his condolences to the relatives of those who died as a result of the attacks.

The US president has also promised Ukraine to continue providing necessary defense assistance, including modern air defense systems.

The White House cited  Biden as saying that he is “in constant contact” with allies and partners to continue to pressure Russia, make it costly and hold it accountable for war crimes.
