Chinese authorities have stepped up security at the country's airports, following the disappearance of a plane travelling from Kuala Lumpur to Beijing.
Malaysia Airlines flight MH370 disappeared at 02:40 local time on Saturday (18:40 GMT on Friday) with 239 people on board. It had been expected to land in Beijing at 06:30 (22:30 GMT).
Malaysia's transport minister said there was no information on wreckage.
"We are doing everything in our power to locate the plane. There were no indications of sabotage nor claims of a terrorist attack. But the passenger manifest issued by the airline included the names of two Europeans - Austrian Christian Kozel and Italian Luigi Maraldi - who, according to their foreign ministries, were not in fact on the plane. I am still hoping and praying that the plane is found with everyone ok, though for some it might seem impossible but i know theres nothing impossible with God. My dad survived a burning plane he was flying and he survived, the plane was a right off and he was declared missing then dead till he was found a few days after the crash, lets not despair.
