US drones launched a number of missile attacks against the South Waziristan Agency of Pakistan overnight, killing at least 21 people and wounding an unknown number of others. The strikes destroyed two homes and a religious school in the tribal area as well as a vehicle.

The victims of the attacks were unknown but Pakistani officials say they believe that foreigners were among the slain in the attack on the vehicle. The US, as usual, did not offer any comment on the attacks.

The strikes come just days after a separate attack on South Waziristan which officials say they believe killed Ilyas Kashmiri, a militant faction leader they blame for the 2008 Mumbai attack. It is the second time Kashmiri was “confirmed” killed in a US drone attack, the previous being in September of 2009.
