A blast at Bangkok`s international airport and grenade attacks elsewhere in the city wounded at least seven people on Wednesday, as lawlessness spread amid anti-government protests, officials said, according to AFP.
The explosion at Suvarnabhumi Airport happened a day after demonstrators stormed the airport, forcing it to close down and stranding thousands of passengers.
"At least two people were wounded by a bomb blast at Suvarnabhumi this morning," Petpong Kamchornkitkarn, an emergency medical services official, told AFP.
Two local television stations said a grenade was fired at protesters and that three people were wounded.
A near simultaneous grenade attack on anti-government protesters picketing Bangkok`s old Don Mueang airport, where the prime minister has set up temporary offices, wounded two more people, Petpong said.
Another three people were wounded when two grenades were tossed into a crowd of pro-government supporters on a road to Don Mueang, the site of a clash between rival activists that left 11 hurt on Tuesday, police said.
Prime Minister Somchai Wongsawat moved to premises at Don Mueang after demonstrators occupied the government`s main offices in central Bangkok in August.
The People`s Alliance for Democracy, a protest movement, has led a six-month street campaign against the democratically elected government.
