Iran Suspends US Talks Over Alleged US Violations of Nuclear Agreement

Talks between the United States and Iran on their nuclear memorandum, held in Switzerland, were suspended on June 21, 2026.

The Iranian delegation, represented by officials from the Islamic Republic, refused to continue discussions in Switzerland, citing US breaches of the agreement. The Iranian side emphasized that negotiations on the nuclear program are directly tied to compliance with the signed memorandum. The US delegation did not immediately comment on the allegations, though sources indicate the dispute centers on Iran's nuclear activities and US sanctions.
