Gunmen stormed a luxury hotel in the Libyan capital of Tripoli on Tuesday, killing four foreigners and five guards, and triggered an hours-long standoff that ended when two assailants set off a grenade that killed them, officials said.
A senior State Department official confirmed the death of one U.S. citizen in the attack on the Corinthia Hotel, which sits along the Mediterranean Sea. The official did not provide further details.
The attack, which began in the morning, included a car bombing, said Essam Naas, a spokesman for a Tripoli security agency.
After several hours of a standoff with Libyan security personnel, the attackers threw a grenade that killed themselves and a security guard. Ten people were wounded in the attack, including security guards and guests.
Earlier in the day, Mahmoud Hamza, commander of the so-called Special Deterrent Force, told private satellite television station Al Nabaa that five foreigners were killed, without elaborating, but Naas later revised the casualty toll.
Since leader Moammar Kadafi's ouster and killing in 2011, Libya has been torn among competing militias and tribes vying for power.
The Malta-owned hotel is where the United Nations support mission in Libya holds its meetings. The mission is currently hosting political talks with rival Libyan groups in Geneva, trying to resolve the country's political and security crisis.
