According to Radio Free Asia News, witnesses on the scene stated that a man made his own explosives and originally wanted to throw it into the embassy, but it exploded next to him, damaging a auto.
A witness told Radio Free Asia that a man tried to throw an explosive over the fence at the U.S. compound - but the bomb detonated in the street. AFP journalists said the visa office adjacent to where the blast took place appeared to have resumed operation not long after the incident.
Another witness said seven or eight police vehicles were at the scene and the road next to the large complex has been closed off.
The embassy resumed normal operations at about 1.45 p.m., it said.
Photos on social media showed a large amount of smoke and police vehicles surrounding the embassy shortly after the incident. Other than the bomber, no other people were injured and there was no damage to embassy property.
Staff members at the Indian and South Korean embassies said they were unaware of any unusual incident and were working as normal.
