Four people, including two foreigners, were killed overnight after five bombs ripped through a popular tourist area in Thailand's mostly-Muslim south, police said.
Two, including a Canadian holidaymaker, were killed instantly by the multiple blasts, police said on Sunday, adding that two more later died of their injuries.
A female Chinese tourist was among the dead, officials at Songklanakarin hospital said. Some 62 others were wounded in the blasts, including 11 foreigners, according to police.
"There are four people dead and another 62 people wounded in five bomb blasts last night," said Paitoon Pattanasophon, police chief in Songkhla province, where Hat Yai - southern Thailand's tourist hub - is located.
Police say the bombs exploded almost simultaneously in an area crowded with bars and cafes, as well as at department stores, late yesterday.
Thai television showed bloodied victims lying in restaurants or being led to safety by rescue personnel, as vehicles burned in streets strewn with shattered glass and overturned tables and chairs.
One body was shown covered with a white sheet next to an overturned motorcycle. Dozens of other motorcycles and larger vehicles also appeared to be destroyed.
As day broke, crowds of shocked onlookers stood amid debris and pools of blood at the blast sites. Pieces of motorcycle littered the street outside a bar where one explosion occurred, shredding nearby awnings and peppering walls with bits of shrapnel.
