Two bombs have exploded in the Thai resort of Hua Hin, killing at least one and injured 12, including foreign tourists. The bombs were hidden in plant pots and detonated by mobile phones, the police said, according to the BBC's Jonathan Head.

Hua Hin, a coastal resort on the Gulf of Thailand, is popular with foreign and Thai visitors.

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

Both bombs were planted at a bar in Soi Bintabaht. One eyewitness report said a foreign man with his wife and child had been badly hurt.

"They had bones sticking out of legs according to local people" Edward Wiek said on Twitter.

Security is said to be tight on the resort with a number of emergency services on the scene.
