The Provincial Police Region 9 has ruled out the possibility that two coordinated bomb attacks on Samila beach in the southern province of Songkhla's Muang district on Wednesday night were politically motivated.

Pol Lt Gen Ronnasil Phusara, head of Provincial Police Region 9, said the bombings had no political motive and investigators were looking at other possible motives, including a conflict among groups of local tourism operators.

The explosions occurred at about 10pm on Wednesday, one at the mermaid sculpture, and the other around 200 metres away near the sculpture of a cat and mouse, he said. The tail of the mermaid sculpture broke off while the cat and mouse sculpture was left unscathed by the other explosion, he said. No one was hurt in either incident.

Maj Gen Chatuphon Kalamphasut, deputy chief of the Internal Security Operations Command (Isoc) Region 4, said police were still unsure who was responsible for the attacks. Although some activities by insurgent groups in Yala, Narathiwat, Pattani and four border districts of Songkhla were previously detected in Songkhla, there was no evidence to suggest they perpetrated the bombings, he said.

Songkhla governor Wiranan Phengchan said security was being tightened to reassure tourists visiting Songkhla during the New Year long weekend.

Deputy Prime Minister and Defence Minister Prawit Wongsuwon said earlier in the day that the attacks could be politically motivated but were not linked with the southern insurgency. However, he said the attackers may be based in the far South.

"These attacks are an attempt to simply stir up unrest, given the fact that not a single person was injured," he said, adding that people should wait for the results of the investigation.

Despite Gen Prawit's comments, a security source said the two attacks might be the work of the Barisan Revolusi Nasional (BRN) bent on wreaking havoc among Songkhla businesses during the New Year festival. The BRN tends to choose business districts for its attacks, said the source.

The mermaid sculpture is popular among Thai, Malaysian and Singaporean tourists. 

The source suggested that the attacks could be in retaliation for crackdowns on the trade of smuggled goods in the province's border areas, which the insurgent group engaged in to raise funding.

On Thursday afternoon, two more explosions occurred in Songkhla's Khuan Niang district. Police were also looking into these two incidents.
