NIAMEY (Reuters) - Niger's government has extradited Abdallah Mansour, a former top Libyan intelligence official under toppled President Muammar Gaddafi, to Libya on suspicion of plotting against the government in Tripoli, military sources said.
Mansour was one of a number of senior members of Gaddafi's regime, including the dictator's son Saadi, who fled to neighbouring Niger in 2011 as rebels seized control of the oil-rich north African nation.
Niger had resisted calls from Libya to extradite Saadi.
"Mansour was extradited yesterday to Tripoli. He was arrested and interrogated by the gendarmerie as part of an enquiry into whether he was plotting against the government in Tripoli," said one military official, who asked not to be identified.
Libyan Prime Minister Ali Zeidan said on Friday the government was safe and security was under control, dismissing a statement by a senior army official calling for the parliament to be suspended and the armed forces to "rescue" the country.
A second military source in Niger, who also asked not to be named, said authorities there had found evidence Mansour was plotting "subversive acts" in Libya following a tip-off from the government there.
"Tripoli's accusations were solid and authorities have informed other supporters of Gaddafi in Niger that they should remain calm," the second source said.
Nearly three years after Gaddafi's fall, Libya's government remains fragile. It has yet to draft a new constitution and its armed forces are unable to impose their authority on the brigades of former revolutionary fighters who refuse to disarm.
