National police chief, Jakthip Chaijinda, has not ruled out that those involved came from Thailand's Muslim-majority southern provinces. "We know where they came from, where they went. We believe there are at least 20 people involved in this network," Jakthip said, according to a report by the Mirror.

The Foreign and Commonwealth Office (FCO) said there is a "high threat" from terrorism in the country. It also advised against "all but essential travel to the provinces of Pattani, Yala, Narathiwat and Songkhla on the Thai-Malaysia border".

AN FCO statement added: "Bomb and grenade attacks have been indiscriminate, including in places visited by expatriates and foreign travellers."

The blast comes shortly after explosions hit the seaside tourist resort of Hua Hin on 11 August, killing one Thai woman and one other and wounding 21 people.
