(VOVworld)- An al Qaeda splinter group said it launched a rocket toward the US embassy in Sanaa on Saturday, wounding several guards, to retaliate for a purported U.S. drone strike in a northern province of Yemen the day before. Several hours after the attack, Ansar al-Sharia, an affiliate of al Qaeda in the Arabian Peninsula (AQAP), said on its Twitter account it had targeted the embassy with a rocket, injuring several guards and damaging a vehicle. The group said the attack was revenge for a drone strike on Friday that had seriously wounded children in the northern al Jawf province. The US State Department said it had no indication that the embassy was the target of the attack and that none of its staff were wounded.
