US and Iranian officials have resumed nuclear talks in Oman aimed at reaching a new agreement on Tehran's nuclear program.
Recent remarks from both sides have exposed deeper rifts, casting doubt on the possibility of a potential agreement.
There are disagreements over key issues such as the dismantlement of Iran's uranium enrichment facilities, with the US demanding dismantlement and Iran rejecting this demand as a red line.
Iranian Foreign Minister Abbas Araghchi remains hopeful for a breakthrough in the negotiations but has criticized the US for shifting remarks, while reaffirming Iran's stance on not seeking nuclear weapons.
