At least 18 people were killed, including two children, when three Russian missiles hit a nine-story residential building and a recreation center in the southern Odesa region’s village of Sergiivka on Friday, Ukrainian authorities said.

Another 30 people were injured in the strikes, according to the Ukrainian President’s deputy chief of staff, Kyrylo Tymoshenko.

Authorities said the numbers are likely to rise as they continue search and rescue operations.

The Southern Command of Ukraine’s Armed Forces said the buildings were struck by Kh-22 air-to-surface anti-ship missiles, launched from Tu-22 strategic bombers flying over the Black Sea.

These are the same type of ammunition Russian forces used during an attack that hit a shopping mall in Kremenchuk, central Ukraine on Monday that killed at least 18.
