MANILA  - Police in the Philippines killed 13 members of a criminal gang in a shootout on Sunday, the third violent incident within days amid widespread calls for stricter gun controls. The battle erupted after gunmen in two vehicles tried to smash through a police checkpoint near the town of Atimonan, according to the national police headquarters’ operations centre. A police statement said one senior police officer was wounded and taken to hospital, and 10 firearms were recovered from the gang members, including an M16 assault rifle. Provincial police chief Senior Superintendent Val de Leon said the road block was put up following a tip-off from a police informant that the gang was to pass through the area on the way to Manila “to make a major hit”. “The information we received came from a very reliable informer, and this is a big accomplishment,” de Leon said.
