Air defense systems were engaged in the early hours of Wednesday in repelling a Russian air attack for a second night in a row in the Ukrainian southern port of Odesa, the region's governor said.
"Do not approach the windows, do not shoot or show the work of air defense forces," the governor, Oleh Kiper, said on the Telegram messaging app.
All of the eastern part of Ukraine was under air raid alerts, starting soon after midnight on Wednesday.
