One woman has died and at least 20 people have been injured after two bombs exploded in a popular Thai tourist resort.

The explosives, believed to have been placed in plant pots, went off in the Hua Hin resort earlier today.

Reports on social media have suggested two British people are hurt, among nine injured foreign tourists.

The second bomb exploded near a bar at about 10:20 p.m (1320 GMT), killing a Thai woman and injuring eight foreigners and one other Thai person, local deputy police chief Samer Yousamran said.

The injured are being treated at a local hospital, he said.

Writing on Twitter, charity founder Edwin Wiek said: 'At #HuaHin hospital. Seems 5 foreigners injured, 2 british, 3 of unknown nationality.'

He later added: ' Latest update: #Huahin #bomb total 23 injured, 1 dead. At least 9 foreigner under the injured.'

It is believed two of those injured are Dutch, while another is a German woman aged in her 20s.

The first bomb went off about twenty minutes earlier about 55 yards away from the second bomb, he said. Nobody was injured in the first explosion.

The attacks took place a day before the Queen of Thailand's birthday - a public holiday

Hua Hin is located in south Thailand where there is a long-running conflict between the government and insurgents

Police are investigating and as yet do not know the motive or the identity of the bombers, he said.

The timing suggested it might be an effort to embarrass the military government that took power two years ago.

Junta chief and Prime Minister Prayuth Chan-ocha on Wednesday night took credit for bringing stability back to Thailand after an extended period of unrest.

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.

Police believe that explosion was related to a local dispute.

Reports on social media suggest one woman has died while 10 people, including foreigners, have been injured

Police say no one was injured in the first explosion but the second killed a Thai woman

Edwin Wiek wrote on Twitter he had been told two British people were among the injured

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.

Thailand's 88 year-old King Bhumibol Adulayadej, the world's longest reigning monarch, and his wife Sirikit are in hospital in Bangkok but have resided in recent years in Hua Hin at the Klai Kangwon Palace royal palace, which translates as "Far from Worries Palace".

King Bhumibol has received treatment for an infection over the past month in a Bangkok hospital, the Royal Household Bureau said on August 1.

Reports on social media have suggested a foreign couple with a child were badly injured, with 'bones left sticking out of their legs'.

Another Twitter user claimed a woman selling salad in the area was killed.

The explosions occurred within around 30 minutes of each other and the pots were said to have been around 55 yards apart.

A spokesman for the British Foreign Office said: ' We are seeking further information following the incident in Hua Hin, Thailand, and stand ready to provide assistance to any British nationals.'

It is thought more than 6,500 people, including Buddhist monks, teachers, troops and separatist insurgents have been killed since 2004 in the long-running conflict, although tourist destinations have rarely been affected.

Police are currently conducting forensic investigations at the site, using torches to examine the scene.

The resort is popular with both foreigners and locals, and hosts international jazz, car and kite festivals every year.

It is also famous for its fishing opportunities while its shallow and warm waters provide good conditions for kite boarding and surfing.

Much of the site has been cordoned off, including this motorbike modified to sell food
