US intelligence agencies reportedly have concerns that Israeli spy services may be conducting surveillance targeting American officials involved in negotiations related to Iran. According to reports cited by multiple outlets, assessments indicate increased monitoring of senior US figures and heightened counterintelligence risk. The surveillance focus is described as aimed at gaining insight into US negotiating positions and related discussions tied to the Iran talks. The reporting also links the issue to broader strains in US and Israeli goals regarding Iran, suggesting that differing national priorities could affect the level and nature of cooperation between the two countries, including areas involving military coordination. Neither outlet provides specific evidence publicly confirming the activity, but both describe intelligence assessments that the matter has become more serious. The claims therefore center on intelligence concerns rather than confirmed outcomes, with the issue framed as a counterintelligence challenge for US agencies amid ongoing diplomacy involving Iran.
