Russian forces have used a variety of missiles and air-launched weapons against several regions of Ukraine in the past 24 hours, according to the Ukrainian military.
It said the Mykolaiv and Kherson regions in the south and Kharkiv in the north came under fire.
There has been an uptick in the use of air-launched missiles and bombs by Russian forces in recent days.
The Ukrainian military said that Russian "strategic aircraft launched missile attacks on Ukraine's southern regions overnight. The enemy struck Mykolaiv region with five X-22 missiles, and Kherson region with one missile."
X-22 missiles: The X-22, also known as the Kh-22, is a powerful missile originally designed to destroy large ships. It is also frequently inaccurate. X-22 strikes have been responsible for heavy civilian casualties in Ukraine.
