Kabul, Afghanistan (CNN) -- The United States and Afghanistan signed a landmark deal Sunday that affords Afghan authorities an effective veto over controversial special operations raids. A bid to end visceral Afghan anger over raids on private residences, the deal prevents NATO's International Security Assistance Force (ISAF) from conducting such operations without the explicit permission of Afghan officials, said a senior NATO official. It was not clear, however, whether the deal ceded 100% of U.S. capabilities over special forces operations, ISAF's key tactic against the insurgency. From now on, an Afghan review group will have to authorize an operation before it goes ahead, the official said.
