Thailand hit with string of blasts; at least four killed, several injured

 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.

Hours after two bombs exploded in the Thai seaside resort of Hua Hin killing one woman and injuring 10 people, another blast in southern Bangkok killed at least one person and caused multiple injuries on Friday.

According to reports, the explosion took near a water police station in the city of Surat Thani which lies about 600 metres south of Bangkok.

Earlier, the explosions happened ahead of a public holiday to mark the birthday of Queen Sirikit.  The second bomb exploded near a bar at about 10:20 pm (1320 GMT), killing a Thai woman and injuring eight foreigners and one other Thai person.

In a separate incident earlier on Thursday, a bomb exploded at a market in the southern Trang province in Thailand, injuring six people, police said.

Thais voted less than a week ago in a referendum to adopt a military-backed constitution, the first test of Prime Minister Prayuth Chan-ocha at the ballot box since he seized power in a coup in May 2014.
