At least seven people were shot dead on Friday by a 14-year-old student in Nonthaburi province, a northern suburb of the Thai capital Bangkok.

BANGKOK, Aug 7 (Reuters) - A teenage gunman killed at least five people and himself at school on the outskirts of Thailand's capital after fatally shooting his grandparents, police said, in the country's worst mass killing in nearly four years.

State police chief says they can act only if Thai authorities provide information on the claim about the men who killed five Thai security personnel recently.
