A group of former rebels in Libya said Thursday it had \"arrested\" Prime Minister Ali Zeidan, after he was seized by gunmen from a Tripoli hotel in a dawn raid. The Operations Cell of Revolutionaries, which in principle reports to the defence and interior ministries, said on Facebook it had seized Zeidan \"on the prosecutor\'s orders\". The premier \"was arrested under the Libyan penal code... on the instructions of the public prosecutor\",  the group said.
