Ed Snowden has disappeared from his hotel

Edward Snowden, 29, checked out from his hotel on Monday. His whereabouts are unknown, but he is believed to be still in Hong Kong.
Earlier, he said he had an "obligation to help free people from oppression".
It emerged last week that US agencies were gathering millions of phone records and monitoring internet data.
A spokesman for the US Office of the Director of National Intelligence said the case had been referred to the Department of Justice as a criminal matter.

Meanwhile a petition posted on the White House website, calling for Mr Snowden's immediate pardon, has gathered more than 30,000 signatures.

However an opinion poll commissioned by the Washington Post suggests a majority of Americans think government monitoring of phone records is acceptable if the aim is to fight terrorism.
