BANGKOK - ANTI-government protesters started on Monday to abandon the prime minister's offices in central Bangkok, which they have occupied since late August, a spokesman for the demonstrators said.

Supporters will now move to Bangkok's airports to reinforce a crippling week-long blockade, said Ms Anchalee Paireerak, a spokesman for the People's Alliance for Democracy protest movement.

'It's too risky to stay at Government House because of repeated attacks against us,' Ms Anchalee told AFP. 'All of us have started to move now, we expect to complete the movement this evening.'
