Thai police have said several explosions in the popular upscale tourist resort of Hua Hin, which left up to four people dead and injured 20 others, were acts of local sabotage, according to the BBC.

"It is local sabotage that is restricted to limited areas and provinces," national police deputy spokesman Piyapan Pingmuang told reporters in Bangkok.

He said at least 11 bombs, many of them twin blasts, have hit five southern provinces in the past 24 hours.

The popular upscale tourist resort of Hua Hin was hit by least four explosions last night while two small bombs also exploded in the resort island of Phuket today.

The bombs that exploded yesterday in Hua Hin killed one Thai woman and wounded 21 other people, nine of them foreigners, Thai police said.

No group has claimed responsibility for the attacks.
