BANGKOK (AFP) - At least seven people were killed and about 100 injured when a man lobbed a hand-grenade into a busy Buddhist temple compound in northeastern Thailand during a celebration, police said Sunday. Local police in Nong Bua Lam Phu province in the rural Issan region said a dispute erupted between young men late Saturday as religious ceremonies to celebrate a new Buddhist pavilion led to traditional music and dancing. "A group of people came for Mor Lam," said Police Colonel Thammajak Kongmongkol, referring to traditional Issan song and dance. "They had an argument, before a person threw a hand-grenade into the crowd." Thammajak said eight people were killed and 97 injured when the M-26 grenade was hurled at the crowd just before midnight, but hospital officials treating the wounded put the death toll at seven and the injured at 111. A nurse at Nong Bua Lam Phu provincial hospital said that most of the injured were suffering from shrapnel wounds, with none in serious condition.
