At least two people have been killed and another 11 wounded after a plane was forced to make an emergency landing in Burma, officials say. Two British nationals are believed to be among the injured. The Air Bagan plane carried more than 60 passengers. It was on its way from the city of Rangoon to Heho airport in Shan state when it crash-landed about 3km (two miles) from the runway. Reports say a fire in one of the engines may have caused the accident. Burmese government officials have confirmed a passenger was found dead inside the plane. A motorcyclist near Heho airport was also killed when the Fokker jet made its emergency landing in thick fog in a rice field. The UK Foreign Office said it was working with Burmese authorities to establish whether two of the foreigners wounded in the crash were British. "Our acting consul is en route to Heho Airport and the charge d'affaires has been deployed to Rangoon airport as we understand that some passengers involved in the incident are being flown there," a UK Foreign Office spokesman said. Two pilots were also among the injured, who are reported to have been taken to Sao San Tun Hospital in Shan's capital, Taunggyi. "The cause of the accident is not clear yet. Only the pilots will know the cause, but we can't contact them yet as they have been sent to hospital," Air Bagan spokesman Ye Min Oo said in a statement. Sources told AFP news agency a fire had started in one of the engines. The plane broke in half when it crashed, eyewitnesses said. Heho is the gateway to the popular destination of Inle Lake in Shan state. Air Bagan is one of handful of privately owned carriers flying domestic routes in Burma. The airline operates two Fokker-100 jets, which are no longer being manufactured.
