Two British military members were killed and another four people wounded in a "serious shooting incident" at an army base in Northern Ireland, police said. No group immediately claimed responsibility for the attack, which occurred at an army base in Massereene, CNN reported. The shooting happened late Saturday in Massarene, in County Antrim, one of the six counties that make up Northern Ireland. Two military personnel and two civilians were taken to a hospital in Antrim with serious injuries, a police spokeswoman said. No group immediately claimed responsibility for the attack, which occurred 200 yards away from a police station where suspected militants are believed to have been detained and questioned recently.
