Ukrainian officials said Russian forces had struck near the town of Lviv in western Ukraine, without elaborating. Maksym Kozytsky, head of the Lviv regional military administration, said: “There have been three powerful explosions near Lviv by Velyki Kryvchytsi, now there is an air alarm, so keep your cool and stay in a shelter.” “The Russian army has hit Lviv,” Lviv Mayor Andriy Santovi said on Twitter. “We are waiting for information from the Military Command. Stay in the shelters.” Explosions were heard on the street in the center of Lviv. Sadovyi warned in another tweet that there could be more casualties after explosions were heard in the city. “The bombing is likely to happen again. Stay in the shelter!” wrote the mayor on Twitter. At least two rockets hit Lviv on Saturday and at least five people were reported injured, according to Kozytsky. He added that there were still threats of more rocket attacks, according to a post on his official Facebook account. “No information has been confirmed about a residential building or other infrastructure,” Kozicki said.
