Thailand's government spokesman says an emergency Cabinet session will include talks about whether to impose a state of emergency to restore order in Bangkok.

The spokesman, Nattawut Sai-kua, said the Cabinet will also consider enacting the Internal Security Law when it meets later Thursday.

An emergency decree would give the prime minister authority to use the military to restore order and to suspend certain civil liberties.

The security law is a separate measure that would enable officials to bar public assembly and "suppress" actions considered harmful to national security.

Prime Minister Somchai Wongsawat on Wednesday resisted demands from the army chief to resign as anti-government protesters shut Bangkok's two airports.
