Hospitals told ABC three victims were Dutch, seven were German, Austrian or Italian and one person's nationality remains unknown.

Authorities are said to have confirmed one fatality and said three of those injured are in a serious condition, according to Channel News Asia.

No group has yet claimed responsibility for the fatal attacks.

Thailand's public broadcasting network reported 20 people were injured in the blast, which went off at 10.50pm local time.

Edwin Wiek, founder of the Wildlife Friends Foundation in Thailand, is at the Hua Hin hospital.

He said: "At #HuaHin hospital. Seems five foreigners injured, two British, three of unknown nationality."

A Foreign Office spokesperson said: "We are seeking further information following an incident in Hua Hin, Thailand.

"We stand ready to provide assistance to anyone British involved."

Wiek was at the scene around 10 minutes after the blast.

He told ABC: "There was a lot of blood, towels, tissues, I mean all kinds of stuff people use to stop the bleeding of wounded people.

"I saw that on different sides, about 100 metres away from each other... where tourists are going to have drinks and walk around, two bombs went off that were planted in pot plants.

"One [was] at an intersection, another one in front of a bar, next to a temple."

Later he added: "Besides two English women, one young German girl is injured in #HuaHin #Bomb. Age around 20 years.

"The #HuaHin hospital says two injured foreigners are from the Netherlands."

The bombs are said to have been 50 metres and 30 minutes apart.

Both explosions were set off from mobile phone devices planted at a bar in Soi Bintabaht.

One of the devices was reportedly planted in a flowerpot.

A female food vendor whose cart was parked in front of the bar was reportedly killed.

Thai Police Col. Sutthichai Srisopacharoenrat said two of those injured are tourists, but their nationalities are unknown.

One eyewitness report said a foreign man with his wife and child had been badly injured.

Edward Wiek added on Twitter: "[They] had bones sticking out of legs according to local people."

Brit Mark Gainsford told the BBC he had been in a bar near the blasts: "I heard people shouting 'Bomb! Bomb!' but I didn't hear any blast.

"I ran out to see if I could help. I saw eight to 10 people injured, on the floor. The police arrived very quickly."

Security is said to be tight on the resort now as it reels from the aftermath, with a number of emergency services on the scene.

A number of police checkpoints have been set up in and around the town.

Local media outlets shared photos allegedly showing injured people at a nearby hospital.

Twin bombings are said to be common in Thailand's southern-most provinces, with armed separatists wreaking havoc for 12 years - but they rarely affect tourist hotspots.

The explosions came ahead of a long weekend of celebrations in Thailand.

Friday is the Queen's Birthday and a public holiday in the country.

Hua Hin, situated about 90 miles southwest of Bangkok, is expecting a number of visitors over the bank holiday weekend and is said to be the preferred home of King Bhumibol Adulyadej.
