Pakistan has given the U.S. embassy 40 days to remove 250 U.S. officials.

Pakistan says the U.S. officials are involved in high-level espionage and anti-state activities.

U.S. Ambassador to Pakistan, Cameron Munter, cut short his vacation to deal with the situation.  The situation has gotten worse in Pakistan, because the United States has greatly increased the number of drone attacks.  Pakistani officials, and independent observers, say the majority of people killed in the U.S. drone attacks are civilians.  In some cases the target of the attack is totally missed, and dozens of bystanders are killed.  U.S. officials have dismissed independent investigations that show that several hundreds of children have been killed.
