Senior US officials grew alarmed in early April 2026 that Israel was plotting to assassinate two of Iran’s most senior diplomats while ceasefire negotiations were actively underway, according to reporting from the Washington Post. The targets, reportedly, were Foreign Minister Abbas Araghchi and Parliament Speaker Mohammad Bagher Ghalibaf, two figures central to any diplomatic resolution of the 2026 Iran war.

What happened, and why it matters

The 2026 Iran war began on February 28, and its consequences rippled far beyond the Middle East almost immediately. The conflict threatened access to the Strait of Hormuz, through which over 20% of the world’s oil supply passes, and the US moved quickly to pursue diplomatic off-ramps.

High-level talks were held in locations including Islamabad and Qatar, with ceasefire negotiations formally beginning around April 7-8. That window, when diplomats on both sides were engaged in some of the most sensitive talks of the conflict, is precisely when US concerns about an Israeli operation peaked.

Washington did not sit on the intelligence. US officials conveyed warnings to Iran through regional intermediaries, effectively alerting Tehran that its negotiators might be in danger. The move was designed to keep the diplomatic process alive, but it also laid bare a significant fracture between the US and Israel at a moment when both governments officially shared the goal of de-escalating the conflict.
