One person was killed and 20 anti-government protesters wounded by a bomb blast at Bangkok's domestic airport early Tuesday, in the latest incident targeting the demonstrators, local reports said.
The explosion at Don Mueang airport came just hours after the People's Alliance for Democracy (PAD) ended a three-month sit-in at the prime minister's offices in Bangkok following a series of grenade attacks.
The hundreds of protesters abandoning the premier's offices moved to Don Mueang and the main Suvarnabhumi international airport.
"There was a bomb attack at Don Mueang just after midnight (1700 GMT)," an emergency services spokesman told AFP.
The Nation newspaper later reported on its website that one person was killed and a further 20 wounded in the latest attack, quoting hospital sources.
It was not immediately clear if the fatality was also an anti-government protester.
A grenade attack early Sunday on Government House, where the premier's cabinet offices are located, wounded around 50 people, while two protesters were killed in similar blasts there last month.
The attacks prompted the PAD to launch a "final battle" with the government, which has developed into an economically crippling week-long siege of the two airports.
PAD leaders said on Monday that protesters would leave Government House and reinforce the airport vigils, while the official premises would be handed back to the government on Tuesday morning.
