Hijackers forced an airliner to land in Malta on Friday then freed all their hostages unharmed and surrendered after declaring their loyalty to Libya's late leader Muammar Gaddafi.

Television pictures showed two men being led from the aircraft in handcuffs. The prime minister of the tiny Mediterranean island, Joseph Muscat, tweeted "hijackers surrendered, searched and taken into custody".

The Airbus A320 had been on an internal flight in Libya on Friday morning when it was diverted to Malta, 500 km (300 miles) north of the Libyan coast, after one man told crew he had a hand grenade.

Initial reports said one of the men had told crew he was "pro-Gaddafi" and that he was willing to free all passengers if his demands were met. It was unclear what the demands were.

A Libyan television channel reported it had spoken by phone with a hijacker who described himself as head of a pro-Gaddafi party. Gaddafi was killed in an uprising in 2011, and Libya has been racked by factional violence since.

Buses were driven onto the tarmac at Malta International Airport to carry away 109 passengers, as well as some of the crew. Television footage showed no signs of struggle or alarm.

After passengers had left the plane, a man briefly appeared at the top of the steps with a plain green flag resembling that of Gaddafi's now-defunct state.
