A man armed with an automatic weapon fired shots at the U.S. Embassy in Sarajevo on Friday, hitting a police officer before authorities shot and wounded him, U.S. and local authorities said.

The gunman was wounded in the left leg and was not considered seriously injured, said Biljana Jandric, a spokeswoman for Sarajevo’s Kosevo Hospital.

Local media said the gunman was a 23-year-old from Sandzak, Serbia. His motives were unknown.

The gunman managed to hit the Embassy building several times, according to a statement from the Embassy. He also shot a police officer assigned to protect the Embassy, hitting him in both kneecaps; the officer later underwent surgery for injuries that were not life-threatening, a police spokesman said.

The Embassy was immediately secured when the shooting began and all of its employees are safe, the statement said.

Bosnia’s TV1 broadcast footage of a bearded man in a long dark jacket pacing in front of the Embassy with an automatic weapon. A single shot is heard as the man falls to the ground, and he was later seen moving his head while surrounded by law enforcement officials.
