A suicide bomber attacked a police station in southwestern Afghanistan early Saturday, killing two people including a policeman, a provincial official said. The attack took place in Nimroz province, which borders volatile Helmand -- which sees some of the worst violence of the Taliban-led insurgency against the US-backed government -- as well as Iran and Pakistan. "At around 9:50 am, a suicide attacker who had strapped explosives to his body detonated his charge in front of the first police station in Zaranj city," provincial governor Ghulam Dastagir Azad told a foreign news agency. "So far, one policeman and a civilian are dead," he said, adding that three policemen were also wounded in the attack. No one immediately claimed responsibility for the attack in Nimroz, where Taliban militants have been increasingly active in recent months.
