The CIA's operations in Lebanon have been badly damaged after Hezbollah identified and captured a number of U.S. spies recently, current and former U.S. officials told The Associated Press. The intelligence debacle is particularly troubling because the CIA saw it coming.

Hezbollah's longtime leader, Sheik Hassan Nasrallah, boasted on television in June that he had rooted out at least two CIA spies who had infiltrated the ranks of Hezbollah, which the U.S. considers a terrorist group closely allied with Iran. Though the U.S. Embassy in Lebanon officially denied the accusation, current and former officials concede that it happened and the damage has spread even further.

In recent months, CIA officials have secretly been scrambling to protect their remaining spies - foreign assets or agents working for the agency - before Hezbollah can find them.

To be sure, some deaths are to be expected in shadowy spy wars. It's an extremely risky business and people get killed. But the damage to the agency's spy network in Lebanon has been greater than usual, several former and current U.S. officials said, speaking on condition of anonymity because they were not authorized to speak publicly about security matters.
