In the popular resort town of Hua Hin four bombs exploded over the last 24 hours. Several blasts also hit the island of Phuket on Friday.

No group has said it carried out the attacks, but suspicion is likely to fall on separatist insurgents.

The timing is sensitive, as Friday is a holiday marking the queen's birthday.

Where have there been blasts?

The attackers appear to be focusing on areas where tourism is significant and reports of sporadic blasts are still coming in. So far the locations include:

Four blasts over 24 hours in Hua Hin where two people have died
Two blasts in Surat Thani where one person has died
Two blasts in the tourist beach town of Patong on Phuket island
One blast in Trang where one person has died
Blasts in the beach province of Phang Nga
