A hijacker seized an Egyptian airliner and forced it to land in Cyprus on Tuesday, but nearly all of the passengers were quickly released and officials said the incident was not linked to terrorism.

Searches by Cyprus police found no explosives on the hijacker of an EgyptAir plane diverted to the island or inside the aircraft, a police source told AFP.

The hijacker, who is in custody after surrendering to police following a six-hour standoff at Larnaca airport, had claimed to be wearing an explosives belt, Egyptian officials said.

Counter-terrorism police frisked the hijacker on the tarmac then interrogated him for more than an hour before boarding the plane and searching it with sniffer dogs.

A government source told AFP the hijacker had demanded to see a Cypriot woman, his estranged lover who lives on the island.

The EgyptAir plane landed at the airport in the southern coastal city of Larnaca at 8:50 am (0550 GMT), after the hijacker had contacted the control tower 20 minutes earlier to demand the diversion.

Egyptian civil aviation said he had threatened to detonate an explosives belt on the Airbus A-320, which had been headed from the Mediterranean coastal city of Alexandria to Cairo.

Most of the passengers were allowed to disembark after the plane landed. Egypt's aviation minister Sherif Fathy told a press conference that the captain, a co-pilot, an air hostess and a security guard remained on board, along with three passengers.

EgyptAir had previously said that negotiations with the hijacker" had resulted in "the release of all the passengers, except the crew and four foreigners."

An AFP correspondent later saw at least seven people descend from the aircraft, including some dressed in what appeared to be crew uniforms.

The plane had been carrying 21 foreigners including eight Americans, four Dutch citizens, four Britons and a French citizen, an Egyptian civil aviation ministry statement said.

Fathy said there had been 55 passengers on board the plane and that the hijacker had demanded it land in either Turkey or Cyprus.

"He had no gun or anything. We don't know yet whether his (explosives) belt is real but for the safety of passengers we are dealing with it as real," Fathy said.

Cyprus President Nicos Anastasiades told reporters the incident appeared to be motivated by personal reasons.

"The hijacking is not terrorism-related," he told a joint news conference with the visiting president of the European Parliament, Martin Schultz.

Asked about reports that the hijacker had demanded to see a Cypriot woman, Anastasiades said: "Always there is a woman."
