US President Joe Biden warned Russia against using chemical or tactical nuclear weapons during the war in Ukraine.

Ukrainian President Volodymyr Zelensky on Wednesday promised "victory" on a visit to the strategic city of Izyum that was recently recaptured from Russia by Kiev's army in a lightning counter-offensive.

Ukraine said Monday that its forces regained yet more ground in the past 24 hours and retook an area seven times the size of Kiev this month, as Russia responded with strikes on some recaptured areas.

He wrote on the Telegram channel that Ukrainian forces have recovered more than 3.000 square kilometers of territory this month and are continuing their offensive.

Ukraine has announced fresh gains in its counter-offensive, including the recapture of the strategic city of Izyum in the country's east, where Kiev accused Russia of carrying out reprisal strikes against electricity infrastructure.

The Ukrainian army continues its successful offensive in the Kharkiv region in northeastern Ukraine, Reuters reported.
