By Yantoultra Ngui and Nguyen Phuong Linh KUALA LUMPUR/PHU QUOC ISLAND, Vietnam (Reuters) - Malaysia Airlines said it was "fearing the worst" on Sunday for a plane carrying 239 people that went missing more than 24 hours ago, as the government said it was investigating four passengers who may have held false identity documents. There were no reports of bad weather and no sign of why Flight MH370 would have vanished from radar screens off the coast of Vietnam about an hour after it took off from Kuala Lumpur bound for Beijing early on Saturday morning. European officials said it appeared two people on board were using stolen passports and Malaysian Transport Minister Hishamuddin Hussein said authorities were also checking the identities of two other passengers. "I have indicated to our intelligence agencies and I have also spoken to international intelligence agencies for assistance." He said help was also being sought from the U.S. Federal Bureau of Investigation (FBI).
