Authorities in Afghanistan say they have arrested four foreigners suspected of plotting terrorist attacks.
Government officials say the four men - one from Iran and three from Pakistan - were picked up after they crossed illegally into Afghanistan's Nimroz province from neighboring Iran this week. At least one of the suspects was believed to be headed to Kandahar province in southern Afghanistan.
Officials in Kabul and Kandahar say the four men are suspected terrorists, but gave no details about their targets or methods. Attacks by militants have increased in Afghanistan in recent months, primarily in southern and eastern regions where U.S.-led coalition forces are hunting remnants of the Taleban and al-Qaida fighters.
Afghan authorities have blamed the increase in suicide attacks and car-bomb explosions on foreign insurgents.
