Three bombs have exploded almost simultaneously in southern Thailand, killing two people and injuring dozens.
Several shoppers were wounded in the supermarket blast
Two of the blasts occurred in the city of Hat Yai, where the airport and a supermarket were targeted.
Another bomb went off outside a hotel in the town of Songkhla, some 40km (25 miles) to the north.
Over the past year more than 600 people have died in Thailand's largely Muslim south, in attacks officials blame on Islamic separatists.
Both victims in Sunday's violence were killed when a bomb exploded near a check-in counter at Hat Yai airport.
The city is the main transport hub for the far south, with most flights bound for other destinations inside Thailand.
At the same time, another bomb exploded in front of the Carrefour supermarket - part of a French-owned chain.
At least 40 people were injured in the two blasts - three are said to be in a critical condition.
The third explosion, in Songkhla City, is thought to have been caused by a bomb placed on a motorbike. There were no casualties there.
Security officials were on high alert because of intelligence reports warning of a car bomb.
The BBC's Kylie Morris in Bangkok says Sunday's attacks represent a further deterioration of security in the south, where violence is normally directed at soldiers, police, teachers and local authorities.
The Thai government has been criticised by human rights groups and Muslim countries over what they call heavy-handed tactics in the south.
On Wednesday, Prime Minister Thaksin Shinawatra indicated he might reconsider his approach to dealing with the unrest.
