BANGKOK - Public Health Minister Witthaya Buranasiri on Sunday unveiled updated casualties of the southern Yala province's bombs, saying a total of 11 people, six men and five women, were killed and 127 wounded.

Of the total injured, 10 were in serious conditions, most of them from burns and bomb shrapnel, he said.

The three deadly bomb blasts took place at a hotel in a busy area of Yala city Saturday noon. The first batch of explosives which was planted in a parked pickup truck exploded 20 minutes before the second and third bombs hidden in motorcycles were detonated.

It was when onlookers were gathering at the first blast site and the authorities rushing to check the incident that the two later bombs went off.  

Several shop houses near the blast site were on fire and many parked cars and motorcycles were damaged by the powerful explosions.

Since the resurgence of insurgency in January 2004, over 11,000 violent incidents have happened in the southernmost provinces of Yala, Pattani and Narathiwat. Altogether over 5,200 people, mostly villagers, have been killed in violent incidents instigated by suspected secessionists in these Muslim-majority provinces which were once independent sultanate of Pattani before being annexed by predominantly Buddhist state in 1909.
