Iran’s official news agency said armed men have killed 14 border guards in clashes near the frontier with Pakistan.
IRNA said authorities were investigating to determine whether the attackers were drug smugglers or armed opposition groups, both of which have occasionally ambushed Iranian troops.
The clashes took place on Friday night in a mountainous region outside Saravan, a town in southeast Iran on the border with Pakistan. IRNA said five other Iranian guards were wounded in the attack.
