“On Nov. 28, a Twitter account linked to al Qaeda in the Arabian Peninsula (AQAP) claimed credit for bombing the US Embassy in the Yemeni capital Sanaa during the evening of Nov. 27, coinciding with Thanksgiving, using two improvised explosive devices (IEDs). The last time AQAP has claimed credit for directly targeting the US Embassy in Sanaa was in late September, after fighters from the terrorist group launched rockets that reportedly fell about 100 meters away from the embassy.”
