Anti-government protesters in Thailand said that an explosive was hurled overnight at their sit-in outside the prime minister's office, killing one and wounding 23. One of the protest leaders, Amorn Amornratamanon, said the blast occurred shortly after 3 a.m. Thursday. He says the explosive was thrown inside the main gate of the Government House compound, which protesters have occupied since August. Government officials have not worked at the compound since the protest began. Protesters are demanding the resignation of Prime Minister Somchai Wongsawat.
