6 wounded in explosion at Bangkok protest site

Six street cleaners have been wounded by a small explosion at an anti-government protest site in Thailand's capital on Monday, police said. The explosion was caused by an improvised bomb or a giant firecracker that went off before noon Monday when the cleaners from the city hall were changing tree pots on a street island near the rally site in central Bangkok, Police Maj. Nopparuj Jitman told The Associated Press. Two of the workers were seriously injured and hospitalized, Erawan emergency medical services said. The demonstrators have occupied major intersections in Bangkok and blocked off several government ministries, forcing employees to work elsewhere.
