UPDATE: Libya's state news agency says kidnaped Prime Minister Ali Zidan has been freed.
Libyan Prime Minister Ali Zeidan was snatched by gunmen before dawn Thursday from a Tripoli hotel where he resides, the government said.
The abduction appeared to be in retaliation for the U.S. special forces raid over the weekend that seized a Libyan al Qaeda suspect from the streets of the capital.
Zeidan's abduction reflected the weakness of Libya's government, which is virtually held hostage by powerful militias, many of which are made up of Islamic militants.
Militants were angered by the U.S. capture of the suspected militant known as Abu Anas al-Libi and accused the government of colluding in or allowing the raid.
The Reuters news agency reports that a group of former Libyan rebels is claiming it seized Zeidan, because of his government's role in the U.S. raid.
"His arrest comes after the statement by (U.S. Secretary of State) John Kerry about the capture of Abu Anas al-Liby, after he said the Libyan government was aware of the operation," Reuters quotes a spokesman for the group, known as the Operations Room of Libya's Revolutionaries, as saying.
A U.S. State Department spokesperson traveling with Kerry in Brunei Thursday said, "We are looking into these reports and we are in close touch with senior US and Libyan officials on the ground. We are working to determine more details. Our Embassy staff is safe in Tripoli. We have no further details at this time."
A statement on the government's official website said Zeidan was taken at dawn to an "unknown location for unknown reasons" by a group believed to be "revolutionaries" from a security agency known as the Anti-Crime Committee.
The Cabinet held an emergency meeting Thursday morning, headed by Zeidan's deputy, Abdel-Salam al-Qadi.
Abdel-Moneim al-Hour, an official with the Anti-Crime Committee, told The Associated Press Zeidan had been arrested on accusations of harming state security and corruption. The public prosecutor's office said it had issued no warrant for Zeidan's arrest.
A government official said gunmen broke into the luxury hotel in downtown Tripoli where Zeidan lives and abducted him and two of his guards. The two guards were beaten but later released. The official spoke to the AP on condition of anonymity, for fear of retaliation.
The abduction of Zeidan came hours after he met with the family of Nazih Abdul-Hamed al-Ruqai, better known by his alias of al-Libi, the al-Qaeda suspect seized by the U.S. He's being held on a U.S. warship.
In a sign of Libya's chaos, Zeidan's seizure was depicted by various sources as either an "arrest" or an abduction.
That is because the militias are interwoven in Libya's fragmented power structure. With the police and army in disarray, many are enlisted to serve in state security agencies, though their loyalty is more to their own commanders than to government officials and they have often intimidated or threatened officials.
The militias are rooted in the brigades that fought in the uprising that toppled autocrat Muammar Qaddafi in 2011, and are often referred to as "revolutionaries."
