A Libyan security source told CNN a jihadist group that is suspected of carrying out the strike, the Imprisoned Omar Abdul Rahman Brigades, left leaflets at the scene claiming the attack was in retaliation for the death of Libyan al Qaeda No. 2 Abu Yahya al Libi.

“Fortunately, no one was injured” in the improvised explosive device attack, the embassy said.

The blast damaged the front gates, the embassy said.
