The first attack took place at about 6.50am at an ATM of Krung Thai Bank in the middle of town near an intersection in Muang district. The blast destroyed one of four machines as well as lights and walls. A local woman, identified as Alisa Mumohali, 29, who was standing near the machine at the time, suffered cuts to her left leg from pieces of the machine.
The second attack was at a Bank of Ayudhya ATM at the intersection of Udomwithee and Piphit roads. No one was wounded.
Police collected evidence and suspected the bombs were detonated using timers.
Security camera footage showed a hooded man placing the bomb under the Krung Thai Bank machine. The explosion took place five minutes later, followed almost immediately by the blast at the Bank of Ayudhya.
Police also said they had information that two motorcycles would be used to bring bombs to residential areas in Muang Pattani between Sunday and yesterday, but had not discovered any such vehicles prior to the two explosions yesterday morning.
