Militants were seen moving ' ` ` chained and covered with blankets '' into pickups . They were driven to a cave , a source associated with Yemen 's Interior Ministry says . A daring raid by U.S. and Yemeni forces into an al Qaeda stronghold in Yemen freed eight hostages , but not before kidnappers stole away with some Westerners , including an American . The missile , launched 4 miles from the cave , killed all 7 militants , it said . But former hostages say five other captives were moved before rescuers arrived .
