Libyan PM Ali Zeidan has been seized by armed men in the capital, Tripoli, according to the BBC.
The website reported that a statement from the Libyan government said Zeidan was taken from his hotel at dawn "by gunmen to an unknown place for unknown reasons".
Al Jazeera reports that a former Libyan rebel group said it had "arrested" Zeidan after the state allowed the U.S. to capture top al-Qaeda suspect Abu Anas al-Liby in the capital.
The Libyan Revolutionary Operations Chamber said on Facebook it had seized the prime minister "on the prosecutor's orders", adding that the prime minister "was arrested under the Libyan penal code... on the instructions of the public prosecutor".
