March 9 (UPI) -- Oslo, Norway, police have released images of a person suspected in the bombing outside the U.S. embassy in the city on Sunday.
Two images from surveillance video were released showing a person wearing all black with their face covered and carrying a backpack.
Police said the explosion, which shattered a glass door, was from an improvised device set at the entrance to the building. It caused minor damage and no injuries. Police said there are no developments on the person's motive.
Police are also looking at a video posted on Google Maps around the time of the explosion. It showed the former Supreme Leader Ayatollah Ali Khamenei, who was killed by the U.S. and Israeli military action on Feb. 28.
Police are asking for anyone with information about the suspect or who noticed anything unusual between midnight and 2 a.m. CET to contact them. They said they have used dogs, drones and helicopters to investigate the scene.
