At around 9:30 p.m., six bombs were detonated in the Ocean Department Store, in front of the Brown Sugar Pub, a car parking building, a Big C shopping mall, the Lee Gardens Hotel and the Diana Department Store.

This later caused Thai authorities to turn off the mobile phone network to prevent any more explosions.

[3] The attacks had marred a day which was supposed to have been dominated by a military peace rally held in the south.

A number of other civilians were injured and taken to the hospital where some officials complained that there was not enough blood for them, as the Xinhua news agency reported.

While no terrorist organisation took responsibility for the bombings, General Thammarak Isarangkura na Ayudhaya indicated that Thai authorities had expected bomb attacks in Hat Yai sometime between 16 and 20 September to mark the first anniversary of the Gerakan Mujahidin Islam Patani (GMIP) separatist movement, which is a splinter group of the Gerakan Mujahidin Patani (GMP).
