Russian missiles have hit an aircraft repair plant near Lviv in western Ukraine, a city that has become a safe haven for people fleeing the war.
Emergency vehicles raced to the site of the strike, just 6km (four miles) from the city centre, after three loud explosions were heard early on Friday.
No-one was injured in the attack.
It is the closest the conflict has come to Lviv, a key humanitarian supply route and a hub for hundreds of thousands of people who have fled.
Western Ukraine has so far been quieter than the rest of the country. Russia launched its invasion on three fronts - from the north, east and south - leaving cities such as Lviv relatively unscathed.
But there are signs that may be changing, after Friday's strike and a deadly missile attack on a military training base outside the city on Sunday.
"There have been air raid alarms here every morning, but now the strikes are actually landing," Valentin Vovchenko, 82, told the AFP news agency from Lviv. "We fled Kyiv because of the attacks but now they've started to hit here.
