A wave of huge explosions rocked popular resorts in the south east Asian country as crowds flocked to celebrate both its National Day and the Thai queen's birthday. Britons caught up in the carnage spoke of seeing the injured lying in the streets after bombs hidden in plant pots were detonated remotely at busy tourist sites and packed beach resorts. The horrific attacks come just hours after bombs were detonated in the resort town of Hua Hin yesterday, killing one person and injuring 21 others, including two Britons. Today more blasts rocked the resort town, which is 120 miles south of Bangkok and is popular with British tourists, with one near a clock tower. One person was killed in Hua Hin, who is believed to be a woman running a local food stall, and three others were injured.

At the same time emergency services were scrambled to the resort of Patong, on the popular tourist island of Phuket, after a further two bombs exploded there. And another two explosions were heard in Phang Nga, north of idyllic Phuket, indicating that the attackers had plotted a coordinated wave of blasts. British tourist Mark Gainsford, who was on holiday at Hua Hin resort, told the BBC: "I heard people shouting 'Bomb! Bomb!' but I didn't hear any blast. "I ran out to see if I could help. I saw eight to 10 people injured, on the floor. The police arrived very quickly." The clock tower explosion is said to have happened around 9am local time (2am GMT). The first bomb in Phuket exploded near a police box, wounding one Thai man, a police officer said.

The second exploded 300 metres away from the first bomb and nobody was injured. Thai media reported two bombs had also exploded in the southern province of Surat Thani, killing one person and wounding five, in a separate incident on Friday. The bombings appear to have been an attempt to target Thailand's lucrative tourism industry with 10 of the 21 people killed at Hua Hin believed to be foreign nationals. It is thought that Dutch, Austrian, German and Italian nationals were amongst the holidaymakers caught up in the blasts. Authorities this morning released a list of 10 names of foreign tourists the say were injured in the attacks which includes two Dutch men, a Dutch woman, and seven others ranging in age from 16 to 48. The identities have not been independently verified. It is not known how many people have been killed in the fresh blasts or who is behind the attacks. But police say they are "acts of local sabotage" and not linked to Islamic extremism.
