Reporting from Washington—
The CIA was forced to curtail its spying in Lebanon, where U.S. operatives and their agents collect crucial intelligence on Syria, terrorist groups and other targets, after the arrests of several CIA informants in Beirut this year, according to U.S. officials and other sources.
"Beirut station is out of business," a source said, using the CIA term for its post there. The same source, who declined to be identified while speaking about a classified matter, alleged that up to a dozen CIA informants have been compromised, but U.S. officials disputed that figure.
U.S. officials acknowledged that some CIA operations were suspended in Beirut last summer. It's unclear whether full operations have resumed. Beirut is considered a key watching post for turmoil in the Middle East.
Senior CIA officials have briefed congressional staffers about the breach, and Rep. Mike Rogers (R-Mich.), who chairs the House Intelligence Committee, visited Beirut recently to interview CIA officers. Committee staff members want to determine whether CIA operatives used sloppy practices that revealed sensitive sources and methods.

Edit: it is interesting to note also the the cell-phone records trick was used extensively by the Hariri Tribunal.
