While the Obama administration says there was no actionable intelligence that could have prevented the assault on the U.S. Consulate in Libya, there was a heightened threat in the region due to at least four attacks on diplomatic and western targets leading up to the murder of the U.S. ambassador.

"This (the U.S. Consulate) was a place that was targeted months before with an IED (improvised explosive device)," Congressman Mike Rogers, Chairman of the House Intelligence Committee, who has been briefed on the attack and investigation, told Fox News. "It's clearly a target that they wanted to hit and they wanted to cause casualties. I find it -- a little the glaring question of a 9/11 date. It's just too many coincidences here."

On June 6, an IED was thrown at the perimeter of the U.S. Consulate in Benghazi. On June 11, the British ambassador's motorcade came under attack by a rocket propelled grenade or RPG.
