Two bombs exploded in the Thai seaside resort of Hua Hin on Thursday, killing one woman and wounding 10 people, a BBC correspondent tweeted, citing local police.
The bombs were hidden in plant pots and detonated by mobile phones, the police said, according to the BBC’s Jonathan Head.
Authorities are said to have confirmed one fatality and said three of those injured are in a serious condition, according to Channel News Asia.
Thailand’s public broadcasting network reported 12 people were injured in the blast, which went off at 10.50pm local time.
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.”
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.
