The Ukrainian health minister says that 198 people have been killed and more than 1,000 others have been wounded in the Russian offensive.

Health Minister Viktor Lyashko said Saturday that there were three children among those killed. His statement made it unclear whether the casualties included both military and civilians.

He said another 1,115 people, including 33 children, were wounded in the Russian invasion that began Thursday with massive air and missile strikes and troops forging into Ukraine from the north, east and south.

The UN refugee agency says that over 120,000 Ukrainian refugees have left the country since Russia began its attack on its neighboring country this week.

Speaking as Russian troops were engaging in battle with Ukrainian forces in the capital Kyiv on Saturday, the UN Deputy High Commissioner for Refugees, Kelly Clements, said in an interview on CNN the situation was expected to get worse.

“We now see over 120,000 people that have gone to all of the neighboring countries,” she said. “The reception that they are receiving from local communities, from local authorities, is tremendous. But it’s a dynamic situation. We are really quite devastated, obviously, with what’s to come.”
