Norwegian police reported on Sunday an explosion near the U.S. Embassy in the capital Oslo, but said there were no casualties.
The explosion occurred around 1 a.m. local time, Oslo police said in a statement, adding they had no information about the blast’s cause or who was behind it.
“A loud bang/explosion was reported at the scene,” Oslo police said.
The police said it was in contact with the embassy about the incident and that a large number of resources were on site.
“The police are in dialogue with the embassy and no injuries have been reported,” police added.
CBS News has reached out to the State Department for comment.
U.S. embassies have been placed on high alert in the Middle East over U.S. military operations in Iran, and several have faced attacks as Tehran hits back at industrial and diplomatic targets.
But police gave no indication the incident near the embassy in Oslo was connected to the conflict.
