Report that some passengers had stolen passports from Austria & Italy.
Given the timing so soon after the slashing attack in China, I hope the authorities look closely at terror as a possible cause.
Yep. Drudge has headlined a link to the story that there were two stolen passports on board, Italy and Austria, presumably being used by someone else.
It could be someone just stealing them and selling them for the money, but it certainly hints of terrorism.
