Up to five explosions rocked Thailand's troubled south early on Monday morning, injuring dozens of people in a town on the Malaysian border, police in the region said.
Bombs planted at entertainment venues across Sun Ngai Kolok town in Narathiwat province wounded 27 people, police said. Two people were seriously injured in the explosions, but no one was killed, they said.
"It was likely done by militants who target innocent people during new year," said police Colonel Prabphan Meemongkon.
More than 2,800 people have been killed in four years of separatist violence in Thailand's south, which was an ethnic Malay sultanate until Buddhist Thailand annexed it a century ago, provoking decades of tension.
Monday's attacks come one year after blasts hit the capital Bangkok on New Year's Eve 2006, killing three people. No one has yet been charged in connection with those attacks.
