World leaders have pledged military aid and support for Ukraine. Earlier, Mariupol's mayor accused Russia of using a chemical agent on the outskirts of the city.
The war in Ukraine is now in its seventh week, as Russian forces are expected to begin a new big offensive in the east of the country after their retreat from the Kyiv region and other parts of the country revealed growing evidence of human rights atrocities.
Despite Moscow's blanket denials, horrific discoveries of civilian murders, torture and other barbaric acts continue coming to light, with Ukrainian authorities claiming tens of thousands of civilian casualties in Mariupol alone.
Kyiv forces continue to prepare for the renewed assault, while Western nations keep tightening sanctions against Moscow and NATO and some EU countries promise to keep delivering more weapons to Volodymyr Zelenskyy.
