BEIRUT (Reuters) - An Ethiopian Airlines plane with 90 people on board crashed into the sea shortly after taking off from Beirut in stormy weather early on Monday and the airline's chief executive said there was no word of survivors.

The Boeing 737-800, heading for Addis Ababa, disappeared off the radar some five minutes after taking off at 2:37 a.m. (0037 GMT) during a thunder storm and heavy rain. Lebanese President Michel Suleiman said he did not think the plane had been brought down deliberately.

"As of now, a sabotage act is unlikely. The investigation will uncover the cause," Suleiman told a news conference.

Fourteen bodies have so far been recovered near the crash site three-and-a-half km (two miles) west of the coastal village of Na'ameh. Eighty-three passengers and seven crew were on the flight, Transport Minister Ghazi al-Aridi said at the airport.

Ethiopian Airlines CEO Girma Wake said he had spoken with Lebanese authorities who did not confirm there were survivors.

Fifty-four of those on board were Lebanese, 22 were Ethiopian, two were British and there were also Canadian, Russian, French, Iraqi and Syrian nationals.

Marla Pietton, wife of the French ambassador to Lebanon Denis Pietton, was on the plane, the French embassy said.

The Lebanese government declared a day of mourning. Prime Minister Saad al-Hariri visited the airport to meet distraught relatives waiting for news of survivors, some of whom were angry that the plane was allowed to take off in bad weather.
