TRIPOLI, Libya (CNN) -- The United States diplomatic office in the Libyan city of Benghazi was attacked Tuesday night, the embassy in the capital Tripoli said Wednesday.
"Fortunately no one was injured" in the improvised explosive device attack, the embassy said.
The blast damaged the front gates, the embassy said.
"The United States deplores the attack on its diplomatic mission in Benghazi ... we have requested the Libyan Ministry of Interior to increase its security around U.S. facilities in Libya," the embassy said.
The embassy said the attack would not affect the U.S. commitment to Libya.
No one has claimed responsibility for the attack, but it comes less than 24 hours after CNN terrorism analyst Paul Cruickshank predicted such an event in retaliation for the death of a top al Qaeda leader.
U.S. officials said Tuesday that Abu Yahya al-Libi, effectively the terror network's second-highest leader, was dead. He had been focusing on establishing an al Qaeda presence in eastern Libya, several sources told CNN.
A previously unknown group called the Brigades of Omar Abdel Rahman reportedly claimed responsibility for a May 22 grenade attack on an International Committee of the Red Cross building in Benghazi, which is in eastern Libya.
