According to Axios, U.S. Special Envoy to the Middle East Steve Witkoff is set to meet with Iranian Foreign Minister Abbas Araghchi next week in Oslo, Norway, in an effort to revive nuclear negotiations between the two countries. The talks come in the aftermath of last month’s U.S. air and naval strikes on three Iranian nuclear facilities.

A central issue in the upcoming discussions will be Iran’s stockpile of highly enriched uranium—estimated at over 400 kilograms enriched to 60%, nearing weapons-grade levels.
