BANGKOK (AFP) - Thailand's cabinet has been barred from using its crisis headquarters and is working from a secret location, a government official said on Wednesday, a day after the military imposed martial law.

The office of the permanent secretary for the defence ministry told the embattled government it could no longer use the facilities where it had been meeting since opposition protesters surrounded its main headquarters months ago, said the official, who did not want to be named.

"The government is now using a safe house," added the official.
