    A huge bomb believed set by Thai southern insurgents beside a local resident's house went off in Su-ngai Padi district of Narathiwat before Saturday dawn, causing the whole building collapsed without casualties since the householder was outside. Police rushed to the venue and estimated the home-made bomb as large as 10 kilograms.

    Hours later, the police found another bomb laid in field around 50 meters from the damaged house. The 10-kg explosives mixed with nails and metal pieces were found inside an iron box. The police said a Nokia 3310 mobile phone with a Thai SIM card was also found nearby, which showed that the bomber has tried to detonate the bomb for dozens of times.

Local radio media reported that a third bomb installed inside a roadside telephone booth in the same district went off at about noon. But the police said later that it was a fake bomb and was moved by soldiers.

    However, a bomb aimed to kill soldiers on duty went off in nearby Ra-ngae district, severely injuring five soldiers on Saturday afternoon. After a 10-minutes fire exchanging between the attackers and soldiers, the suspected terrorists withdrew from a flourish bamboo forest without anybody detained.

    Two days earlier, Pol. Lt. Gen. Adul Saengsingkaew, commissioner of the Provincial Police Region 9 based in Thai south, told reporters that the government security forces in deep South will continue to intensify their suppression of insurgents in the region, as their networks are already eroding under the pressure of government action.

    Adul said that the insurgency in the country's three troubled southernmost provinces of Pattani, Narathiwat and Yala had been weakening due to the intense crackdown on the part of state security forces.

    "Insurgents can now only launch minor attacks from time to time as the security forces have successfully eroded their networks," the regional police chief said.

    "So, the security forces will continue to press ahead with the practical tactics to get rid of the insurgents in the region," he added.

    At least 1,200 people have been killed since unrest broke out in January 2004 in the mainly Muslim provinces along Thailand's border with Malaysia. The violence was blamed on a complex web of Islamic separatists, local corruption and organized crime. Enditem
