Iran has accused the United States of violating key provisions of the recently signed memorandum of understanding (MoU) during technical-level talks held in Doha, even as global oil prices continued to slide amid hopes of easing tensions.

Deputy Foreign Minister Kazem Gharibabadi said the Iranian delegation raised the issue of the US violating Article 1 of the MoU, which commits both sides to ending war on all fronts. The meetings were mediated by Qatar and Pakistan.

In a separate discussion with Qatari officials and the central bank, the two sides discussed the release of approximately $6 billion in frozen Iranian funds. Iran maintained that it should have the right to use the money for purchasing goods based on its declared needs.

Iran’s Parliament Speaker Mohammad Bagher Ghalibaf also rejected reports that the International Atomic Energy Agency (IAEA) had been granted access to bombed nuclear sites at Fordow, Natanz, and Isfahan, calling such claims false.

Qatar’s foreign ministry spokesperson said the talks made “positive progress” and discussions would continue after the funeral of former Supreme Leader Ayatollah Ali Khamenei.

Meanwhile, Brent crude futures fell over 1 per cent to around $70.84 per barrel, while US WTI crude dropped to $67.75 per barrel. Analysts said easing geopolitical concerns following the Doha talks were weighing on prices.

The developments come as both sides continue indirect negotiations to stabilise the situation after the recent conflict. Further rounds of talks are expected in the coming weeks.
