Iran has reaffirmed its right to continue uranium enrichment ahead of a key meeting in Istanbul with Britain, France, and Germany, where Tehran is expected to face warnings over potential nuclear sanctions, reported news agency ANI.

The talks, scheduled for Friday, will also include the European Union's foreign policy chief, Kaja Kallas, and mark the first high-level meeting since Israel's mid-June strikes on Iranian nuclear and military sites triggered a 12-day war, which ended in a ceasefire on June 24.

"Especially after the recent war, it is important for them [European countries] to understand that the Islamic Republic of Iran's position remains unshakable, and that our uranium enrichment will continue," Iranian Foreign Minister Abbas Araghchi said on Thursday, reported ANI.
