A series of blasts across Thailand targeted the tourist towns of Hua Hin, Phuket and other locations, leaving at least three dead and many injured.
They came hours after twin bombs killed one person in the seaside resort town of Hua Hin, near the capital Bangkok.
On Friday, the town was hit again by multiple blasts. Two explosions were also reported in the popular tourist destination of Phuket.
It comes as Thais celebrate a long weekend for Queen Sirikit’s birthday.
The string of blasts on Friday include:
Two blasts in Hua Hin where one person has died
Two blasts in Surat Thani where one person has died
Two blasts in Phuket where it is unclear how many are injured
One blast in Trang where one person has died
One bomb has been defused by authorities
No group has said it carried out the attacks.
But the BBC’s Jonathan Head in Bangkok says suspicion will probably fall on separatist insurgents who have been waging an armed campaign against the Thai military in the three southernmost provinces.
