Iran has confirmed it will hold nuclear talks with three European powers, the UK, France, and Germany, in Istanbul on Friday. This marks the first meeting since recent escalations in regional tensions, including threats of renewed UN sanctions against Iran if progress on the nuclear deal is not achieved. Iranian officials have expressed frustration towards European nations, accusing them of failing to uphold the terms of the 2015 nuclear agreement. Lawmakers in Tehran have warned of consequences if sanctions are reimposed, including potential threats to regional security and the abandonment of nuclear limits. The upcoming negotiations come as both sides face pressure to reach a comprehensive agreement before the end of August, when a deadline for potential sanctions looms.
