WASHINGTON — Four American military personnel were detained by the Libyan government on Friday and held in custody for several hours before being released, U.S. officials said.
State Department spokeswoman Jen Psaki said President Barack Obama's administration was looking into the incident, but confirmed that "all four U.S. military personnel being held in Libyan government custody have been released."
A U.S. defense official said the Americans appeared to have been checking possible evacuation routes for the U.S. embassy in Tripoli.
The Americans were near Sabratha, an area west of Tripoli that is home to well-known Roman ruins, "as part of security preparedness efforts when they were taken into custody," Psaki said in a statement.
Passport pictures said to belong to the four were posted on Twitter. The identity of the Americans or the authenticity of those photos could not be immediately confirmed.
A Reuters photographer who arrived later at the scene saw a burned out, four-wheel drive vehicle.
"Their car burned out," the security source said. A police official told the photographer the car was set on fire after the arrest, but did not explain the circumstances.
The Americans' second car was stopped by security forces close to Sabratha, a coastal town, the Libyan source said.
Psaki said the United States, which backed the 2011 uprising against Moammar Gadhafi, valued its relationship with "the new Libya."
"We have a strategic partnership based on shared interests and our strong support for Libya's historic democratic transition," she said.
More than two years after the collapse of Gadhafi's rule, the North African country is still in turmoil, with widespread insecurity, rival militias and a burgeoning autonomy movement in the country's east.
The detention takes on greater significance because of the militant attack in Benghazi on Sept. 11, 2012, in which U.S. Ambassador Chris Stevens and three other Americans were killed.
The attacks touched off a political storm in Washington, with Republicans accusing Obama's administration of telling shifting stories about who was behind the attacks.
In October, U.S. forces seized Nazih al-Ragye, better known by the cover name Abu Anas al-Liby, in Tripoli in connection with the bombings of U.S. embassies in Kenya and Tanzania in 1998.
