Bangkok, Aug 12 (AFP/IANS): At least four people have been killed in eight bomb blasts that have hit across Thailand in the past 24 hours, in the resort town of Hua Hin and southern provinces, authorities said.

"Twin bombs at the clock tower killed one and injured three," said Hua Hin district chief Sutthipong Klai-udom, referring to two new blasts in the town today that followed twin bombings there the night before.

As well as the four blasts in Hua Hin, there were two on the tourist island of Phuket today along with one in the island gateway town of Surat Thani, and one in southern Trang on Thursday, officials told AFP.

Around 650 ft away, another two bombs exploded late Thursday night as foreign tourists were leaving local bars to go back to their hotels, Yoosumran said.

At least 11 people -- mostly foreign visitors -- were injured and a woman who had a food vending cart in front of a bar was killed on Thursday night, CNN quoted Yoosumran as saying.

"The bombs were planted on the street where most of the customers are foreigners," he said, adding "And they went off while foreigners started to leave the bars and go back to their hotels."

Both bombs that exploded in Hua Hin on Thursday night were planted inside tree pots, about 164 ft away from each other, near a bar called Johnny's 56, Yoosumran said.

The first bomb went off at around 11 p.m. The second exploded a few minutes later, CNN quoted Yoosumran as saying.

At least one person, a female municipal worker, was killed and four injured on Friday after two blasts went off in in Surat Thani city, according to Chavalit Chanmornoi, a local police captain.

The explosions occured about about 650 ft from each other, and were around 30 minutes apart, CNN reported citing Chanmornoi as saying.
