Iran accused Saudi Arabia of launching an airstrike against the Iranian embassy in Yemen on Thursday, but both media and kingdom spokespeople said there is no proof Tehran's claims are true.
The Associated Press said reporters and photographers could not see any damage at the embassy compound, located in Sanaa. And Ahmed Asseri, a spokesman for Saudi Arabia, said the kingdom would investigate the accusations, but so far, there's "no proof yet" the strike actually occurred, the Washington Post reported.

The chairman of Military Theory at Marine Corps University, Sebastian Gorka, said the matter is crucial because it pits Sunnis against Shiites in open war, and raises the all-important question: "Who's going to control the Middle East?"
He went on, during a Fox News segment: "We have to understand this is a war between two extreme religions," with the end result deciding which entity holds power and influence in the Mideast region.
