Oslo police suspect an explosion at the U.S. Embassy in Oslo on March 8 may be linked to the war with Iran, even though Norway is thousands of miles away from the Middle Eastern conflict.

“It’s natural to see this in the context of the current security situation and that ​this could be an attack deliberately targeting the U.S. embassy,” Frode Larsen, ​head of the Oslo police investigation unit, said during a news conference on March 8.

The blast happened in Norway’s capital city at 1:00 a.m. near the entrance to the U.S. Embassy’s consular section, according to Oslo police.

One eyewitness saw smoke in the area and said the entrance was damaged.

No injuries were reported.

No suspects or persons of interest have been arrested, and the investigation is ongoing.

“One of our hypotheses ​is that this is terrorism, but we are also exploring other options,” Larsen told local media.

Norwegian Foreign Minister Espen Barth Eide said in a statement that the blast is “an ⁠unacceptable act“ that Norway takes ”very seriously.”

“The security of diplomatic missions is very important to us,” Eide said.

The Epoch Times contacted the U.S. Embassy in Oslo and the Department of State for comment but received no response by press time.

The March 8 incident in Norway is the latest in a string of attacks against U.S. embassies in the region since Operation Epic Fury, the United States’ operation in Iran, started on Feb. 28.

On March 7, Katyusha rockets targeted the U.S. Embassy in Baghdad, the first time the building has been attacked in two years.

The attack is suspected to have been planned by Iran‑aligned Iraqi militias who were on a mission to retaliate ​against the United States for killing Iranian leader Ali Khamenei.

A senior Iraqi security official said that the country’s defense ‌system was able to strike down one of the rockets on March 7 and that none landed on the embassy.

It’s not clear whether the rockets caused any damage or casualties in the area, but the senior Iraqi security official confirmed that no Americans were hurt.

The State Department has a “do not travel” advisory in place for Iraq.

Iranian drones targeted the U.S. Embassy compound in Riyadh, Saudi Arabia, on March 3.

That was the same day the Department of State authorized non-emergency U.S. government employees and U.S. government employee family members to leave Saudi Arabia because of the war with Iran, which was causing instability in the region.

The U.S. consulate in the United Arab Emirates was also targeted by drones on March 4.
