All 112 people aboard a Chinese jetliner that plunged into the sea near the northeastern city of Dalian are dead, the airline has said. The news came after searchers worked through the night to find survivors from China Northern Airlines Flight 6136, which crashed around 9.40 p.m. (1340 GMT) on Tuesday, about 20 kilometers east of the resort city of Dalian. "The 103 passengers and nine crew aboard the airliner all perished," said a letter issued by the airline that expressed condolences to the families of the dead. The plane crashed shortly after the captain reported a fire in the cabin, according to state news agency, Xinhua. A flotilla of more than 30 tugs and warships had been searching the murky waters of Dalian Bay for survivors.
