US intelligence services are concerned about an increased threat of Israeli espionage.

Recent reports from US intelligence services have highlighted growing concerns about espionage activities attributed to Israel against the United States, in a context marked by negotiations between Washington and Tehran.

According to information reported by the New York Times and attributed to American officials, US authorities believe that Israeli efforts to obtain intelligence on the American position in discussions with Iran have intensified to the point of causing unusual concern within the intelligence community.

A Defense Intelligence Agency report reportedly raised the counterintelligence threat level associated with Israel from "high" to "critical." This assessment reportedly refers to attempts to gather intelligence targeting U.S. military personnel and government officials.

Among those reportedly under increased surveillance were Steve Witkoff, the US president's chief negotiator, as well as Elbridge Colby and his deputy Michael DiMino.

These concerns seem paradoxical given the particularly close military and security cooperation between the United States and Israel. The two countries regularly share tactical and operational intelligence, especially in the face of regional threats linked to Iran.

However, several US officials believe that Israel is now seeking to better understand the diplomatic intentions of the US administration and the evolution of its negotiation strategy with Tehran. According to these sources, this situation could complicate certain mechanisms for sharing sensitive information between the two allies.

The report also mentions incidents in which US military personnel present in Israel allegedly discovered software secretly installed on their phones, software which could have allowed the interception of communications.

The U.S. Department of Defense has not commented on these reports. The White House, for its part, rejected the accusations, calling them false. Israel has also denied any espionage operations targeting U.S. officials or institutions.

The tensions come as the US president Donald Trump pursues a diplomatic approach towards Iran, while Israeli Prime Minister Benjamin Netanyahu advocates a much firmer line against Tehran and its regional allies.

According to several current and former officials cited in the report, Israel remains one of the United States' most active foreign partners in intelligence gathering. Despite their strategic alliance, both countries continue to rigorously protect their most sensitive information and apply strict security protocols in their communications.
