Ukrainian media and witnesses are reporting multiple explosions in the southern city of Odesa soon after 6 p.m. local time. One witness told CNN that she saw at least one combat plane over the city.
The military's Operational Command (South) said on Telegram that the runway at Odesa's airport had been damaged.
The blasts were heard soon after air raid sirens sounded across the city.
A witness to the explosions told CNN she was about one kilometer (.62 miles) away from the airport when she heard two explosions. She said the attack lasted about 10 minutes and she was still experiencing hearing difficulties because of the noise from the impacts.
