Hundreds of pro-government demonstrators swarmed around a court building Tuesday, forcing the relocation of judges who will rule on the fate of a Thai government beset by protests and a virtual shutdown of international air links.
Judges of the Constitutional Court had to scurry to a suburban courtroom where they are to decide whether Prime Minister Somchai Wongsawat and others in his party committed electoral fraud — a move that would see him banned from politics and his party dissolved.
The protesters followed the judges to the new location, shouting "Fight, fight," as dozens of soldiers carrying riot shields and batons and about 100 riot police guarded the court compound.
Hours earlier, an explosive device was hurled into a crowd of anti-government protesters at Bangkok's domestic airport, killing one person and wounding 22, said Surachet Sathitniramai of the Narenthorn Medical Center.
The court is expected to rule this week, and if the decision goes against Somchai it could dampen protests by the People's Alliance for Democracy, which has been seeking Somchai's ouster through daily protests and the seizure of Bangkok's domestic and international airports.
But it could also inflame pro-government supporters who have been gathering their strength in recent days and widen an already dangerous rift in Thai society, further paralyzing government machinery and draining the economy of millions of dollars.
Late Monday, the explosive device fired from an elevated highway fell among hundreds of protesters, some of them asleep, inside Don Muang domestic airport, Surachet said. A protest leader, Somsak Kosaisuk, said the crowd was hit by a grenade from an M-79 launcher, a battlefield weapon.
It was the third such attack in two days by unidentified assailants targeting the protesters. So far, seven people have been killed and scores injured in bomb attacks, clashes with police and street battles between government opponents and supporters.
