Within 24 hours of a US attack helicopters strike inside Pakistan's Taliban-controlled tribal agency of Mohmand that killed more than 20 Pakistani troops, the Pakistan government has ordered the US to vacate a key airbase in Baluchistan and has closed NATO's supply lines through the Khyber Pass. The Defence Committee of the Cabinet, a Pakistani committee chaired by Prime Minister Yousef Gilani, issued a statement calling for US personnel to leave the Shamsi airbase in Baluchistan province and the closure of NATO's supply chain to Afghanistan.
