Bangkok - A bomb, thrown early Thursday among anti-government protestors gathered at Makkahawan Bridge in Bangkok, injured at least nine people, one of them seriously, radio reports said.
The bomb was thrown at members of the People's Alliance for Democracy (PAD) who have been staging anti-government protests at Makkahawan Bridge since May, this year.
PAD core leader Chamlong Srimuang blamed the attack on the government.
He said that the attack would not stop the PAD from marching on the British Embassy in Bangkok Thursday to demand the extradition of former premier Thaksin Shinwatara.
The PAD is a loose coalition of conservative groups fanatically opposed to a return to power by Thaksin and his political allies.
