In their latest update on the conflict, the Ukrainian armed forces said Russian forces have continued "conducting systematic combat operations using bomber aviation in order to destroy the military and civilian infrastructure of Ukraine. "
"The occupiers use high-powered ammunition and disordered strikes on civilians. Such actions are classified by the International Humanitarian Law as a war crime," the armed forces said in a statement.
Amid heavy fighting in the south, the armed forces said Russian forces continued their efforts to surround the city of Mykolaiv, which is seen as a critical route to the major south-western city of Odessa. They said Russian forces had been held back.
Around Kyiv, the Ukrainian armed forces said Russian forces were trying to get beyond the Irpin River to gain a foothold around the settlements of Bucha and Irpin — two suburbs of Kyiv that have seen intense combat since the invasion began. They said Russian forces were regrouping in order to resume offensive actions in the direction of Kyiv.
The armed forces statement said that in eastern Ukraine, the Russians were focused on recovering from losses inflicted around Kharkiv and Izium. Both cities have seen widespread damage and civilian suffering.
On Monday, according to Lyudmila Denisova, the Human Rights commissioner of the Ukrainian parliament, enemy forces fired on a private minibus in the Izium area. "The fate of the passengers is unknown," she said.
"The enemy is constantly firing at [the city] with aircraft and artillery day and night. There are no possibilities for the delivery of humanitarian aid or evacuation. The number of civilian casualties cannot be determined," Denisova said.
The armed forces acknowledged that in Donetsk Russian forces were having "partial success in some areas due to their numerical advantage."
The armed forces statement said that so far, 77 Russian aircraft, 90 helicopters and nearly 400 Russian tanks had been destroyed. CNN cannot verify the Ukrainian claim of Russian losses.
