Hezbollah Secretary General Sayyed Hassan Nasrallah\'s charges that the Central Intelligence Agency had infiltrated his group in Lebanon were \"empty accusations,\" a US embassy spokesperson said. \"These are the same kinds of empty accusations that we have repeatedly heard from Hezbollah,\" the spokesperson said. \"There is no substance to his accusation,\" he added. \"It appears as if Nasrallah was addressing internal problems within Hezbollah with which we have nothing to do. \"Our position towards Hezbollah is well known and has not changed,\" he said. Sayyed Hassan Nasrallah on Friday said two members of Hezbollah had confessed to being CIA agents and accused arch-foe Israel of turning to the US spy agency after itself failing to infiltrate the party. Nasrallah also said the group was investigating whether a third member of the party had been recruited by the CIA, Israel\'s Mossad or the intelligence service of a European country.
