Twenty-one people, including two children, were killed in air strikes on the besieged northeast Ukrainian city of Sumy, the authorities said.
"The bodies of 21 people, including two children" were found at the site of Monday's strikes, the regional public prosecutor said on Facebook. A previous toll given by the emergency services was nine dead.
"We have already started the evacuation of civilians from Sumy to Poltava, including foreign students," Ukraine's foreign ministry said in a tweet. "We call on Russia to uphold its ceasefire commitment, to refrain from activities that endanger the lives of people and to allow the delivery of humanitarian aid."
Dmytro Zhyvytsky, the governor of the Sumy region, said in a video statement that a second column of civilians would leave Sumy at around 1100 GMT. A short video clip released by presidential advisor Kyrylo Tymoshenko showed a red bus with some civilians on board.
