Two bombs have exploded in the popular Thai tourist town of Hua Hin, killing one person and injuring at least 23 others.
One bomb hidden in a pot plant exploded on a road outside a bar, followed by a second blast just 50 meters away around 20 minutes later.
A Thai woman selling papaya salad at a street cart was killed in the second blast, police in the seaside town confirmed.
Local police said officials were still investigating a motive and the type of explosives used.
Hua Hin’s major hospitals told the ABC 11 foreigners are among the wounded.
Three were Dutch, seven were German, Austrian or Italian, and one person’s nationality remains unknown, the hospitals said.
No Australians are believed to have been hurt in the bombings, which happened ahead of a public holiday to mark the birthday of Queen Sirikit.
The blasts also come days before the one-year anniversary of the last major bombing in Thailand, an attack outside a Hindu shrine in Bangkok that killed 20 people on August 17, mostly foreign tourists.
‘There was a lot of blood’
Photos published in local press showed emergency workers evacuating victims from the area on stretchers, and some foreign tourists with minor cuts and injuries gathered in a local hospital for treatment.
Wildlife Friends Foundation founder Edwin Weik told the ABC he was at the scene around 10 minutes after the blast.
“There was a lot of blood, towels, tissues, I mean all kinds of stuff that people use to stop the bleeding of the wounded people,” he said from Hua Hin.
“I saw that on two different sides, about 100 meters 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.”
Mr Weik said there were no serious injuries in the first blast, but the second bomb caused serious damage.
In a statement, the Department of Foreign Affairs said Australia’s embassy in Bangkok was “in urgent contact with local authorities to determine if any Australians have been affected”.
DFAT said anyone concerned for loved ones in Thailand “should contact the Department of Foreign Affairs and Trade’s 24-hour Consular Emergency Center on 1300 555 135 within Australia or +61 6261 3305 from overseas”.
