The sixth nuclear talks between the United States and Iran, scheduled to take place in Muscat, Oman, have been canceled.

Oman's Foreign Minister Badr al-Busaidi, who played the role of mediator, noted on social media platform X on the 14th that "the meeting between Iran and the United States scheduled for the 15th has been canceled." He added, "Diplomacy and dialogue remain the only path to sustaining peace."

The cancellation of the nuclear talks appears to be due to escalating military clashes between Iran and Israel following a large-scale airstrike by Israel. Earlier, the Israeli military mobilized 200 fighter jets in the early morning to conduct a surprise airstrike on Iran's Natanz nuclear facility in Isfahan, targeting key military commanders and nuclear scientists.

Initially, the sixth nuclear talks were expected to focus on the first official proposal presented by the United States and Iran's response to it. Although specific details of the proposals from both sides are not known, discussions were said to revolve around Iran's uranium enrichment.

The United States has repeatedly stated that it cannot allow uranium enrichment, a critical step in nuclear weapon manufacturing, but Iran has emphasized that it cannot abandon this under any circumstances.
