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