U.S. pulls out more staff from embassy in Libya (AP) NEW YORK - The State Department is further drawing down staff at the U.S. Embassy in Libya for security reasons. A senior State Department official said Thursday that the reduction in personnel at the embassy in Tripoli, which has already been operating with limited staff after the deadly Sept. 11 attack on the U.S. Consulate in Benghazi is expected to be temporary. The official said the security situation would be reviewed early next week with an eye toward restoring the staff "as soon as conditions allow." Ambassador Chris Stevens and three other Americans were killed in the attack.
