A BOMB exploded at Thailand's main government complex as the Prime Minister chaired a meeting, but it caused no casualties and was probably left behind during recent protests, officials said.
The explosion in the Government House compound in Bangkok happened as Prime Minister Abhisit Vejjajiva held a national security meeting attended by the Defence Minister and army and police chiefs.
The device went off as a worker was closing a manhole during security checks at the building, ahead of a national children's day celebration tomorrow, said Mr Pongsak Siriwong, director of the Household and Vehicle Division.
The bomb was believed to have been hidden in a pipe behind the Thai Kufah Building where MrAbhisit was chairing a meeting of the security agencies.
'We may find more bombs in future,' Mr Pongsak said.
Police suspected that the bomb had been left by demonstrators from the royalist People's Alliance for Democracy (PAD) when they occupied the complex in August last year in protest against the previous government.
The PAD left Government House last month after a court verdict led to the collapse of the old government, which was loyal to ousted former premier Thaksin Shinawatra, the protest movement's arch foe.
Police who cleared the compound afterwards said they had found explosives and several kinds of weapons.
Two PAD protesters were killed in grenade attacks on their protest camp at Government House last year. No one has been charged in connection with the attacks.
Mr Abhisit, from the anti-Thaksin Democrat Party, was elected Prime Minister last month after winning the support of defectors from the former ruling People Power Party as well as the party's former coalition partners.
