The CIA dismissed Hezbollah's assertions.
"The agency does not, as a rule, address spurious claims from terrorist groups," CIA spokeswoman Jennifer Youngblood said. "I think it's worth remembering that Hezbollah is a dangerous organization, with al-Manar as its propaganda arm. That fact alone should cast some doubt on the credibility of the group's claims."
Former officials said one of the named officers was considered a rising star at the CIA and had been involved in many important operations in Iraq. Whether or not this employee would be able to continue a CIA career outside the U.S. is unknown. Former officials said it is likely Hezbollah has already shared photographs of the case officers with Iran, its closest ally.
It was not immediately clear whether the exposed CIA officers in Lebanon have been pulled out of the country. The Associated Press is not publishing the names of the officers because they could refer to operatives who remain undercover.
Revealing the identities of CIA officers has happened in the past. The last instance came about one year ago when the name of the CIA's Pakistan station chief was leaked to reporters there. The CIA initially let him stay but eventually decided it was too dangerous for him to remain in the country.
Case officers met with informants at locations more than once, a practice frowned upon because it risks their exposure.
The disclosure indicates that Hezbollah is sending a sharp message to the CIA to stay out of Lebanon, suggesting that it could have captured the CIA officers at any time since it knew their identities. In 1984, Hezbollah kidnapped the CIA station chief in Beirut. He was tortured and later killed.
Al-Manar said the CIA team in Lebanon consisted of 10 officers and all used diplomat cover. The station said their jobs were to oversee intelligence networks in Lebanon.
