The men were arrested Tuesday when a special forces unit raided a compound on the Helmand River just north of Deh Rawood in central Uruzgan province, U.S. military spokesman Col. Rodney Davis said from Bagram Air Base (search), north of the capital.
Davis would not give details about their identities.
About 11,000 coalition troops, including 8,000 American soldiers, are in Afghanistan hunting down fighters loyal to Usama bin Laden's Al Qaeda network, the ousted Taliban government and supporters of renegade warlord Gulbuddin Hekmatyar.
Davis said another U.S. special operations unit recovered a weapons cache Tuesday near Khost in eastern Afghanistan. The cache included two 82 mm mortar rounds and seven 107 mm rockets -- the same kind often fired on U.S. bases. It was not clear who owned the weapons.
