On Wednesday, investigators were scrambling to determine the cause of a plane crash in Tehran, which killed all 176 people on board.

The Ukrainian plane crashed shortly after it took off from Tehran’s International Airport.

The state media in Iran blamed technical issues on the crash and Ukraine ruled out rocket attacks, but officials in both countries have since walked back their statements and are now refusing to speculate on the cause.

But countries all over the world are raising questions, especially about the timing of the incident, which came a number of hours after Iran fired a number of missiles at 2 Iraqi based housing US troops.
