A civilian jetliner crashed in Iran shortly after take-off from Tehran Airport, about an hour after Iran fired missiles at Iraq bases that house U.S. troops.

The crash killed all 176 souls on board the Ukrainian airliner early Wednesday morning local time.

Among the dead are 3 British citizens, 82 Iranians, 63 Canadians, 3 Germans, and 10 Swedes.

Video footage shows smoldering wreckage at the crash site shortly after dawn on Wednesday.

Safety experts said the plane crash was caused by engine problems that were unrelated to the missile attack on Iraq military bases. The airline said the pilot did not declare an emergency.

There were no American casualties or injuries in the missile attacks. The damage was minimal after the Iranians fired 15 ballistics missiles at the Iraqi bases where U.S. troops are stationed.

According to published reports, the missiles struck 2 empty bases in Iraq. The Pentagon was warned before the start of the attack and the bases were cleared of U.S. personnel before the missiles struck.

President Donald Trump assured Americans in a tweet regarding the missile attack late Tuesday night.
