A suicide bomber attacked a police station in southwestern Afghanistan early on 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 AFP.
"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.
The insurgency -- launched after the ouster of the Taliban regime in a US-led invasion in late 2001 -- has intensified over the past two years, despite the presence of about 70,000 international soldiers in the country.
