UN nuclear inspectors have been kept away from a student protest as they landed in Tehran hoping to shed light on Iran’s nuclear programme.
Demonstrators carried pictures of murdered nuclear scientist Mostafa Ahmadi Roshan, who was killed by a car bomb earlier this month.
The head of the inspection team says he wants to resolve all outstanding issues on Iran’s nuclear programme, which the agency has said includes weapons-related research.
Iran has hit back at recent EU sanctions, turning on its head a European move to stop importing crude oil.
Lawmakers are due to vote on a bill that could see Iran switch off the taps, cutting off supplies to the EU within days, and denying countries most dependent on Iranian oil time to adapt.
Iran has repeatedly threatened to close the Strait of Hormuz shipping lane if western sanctions block its crude exports, a move Washington says it wouldn’t tolerate.
The EU accounted for a quarter of Iranian crude oil sales in the third quarter of last year. But analysts say the global market should not be too disrupted if supplies are halted, as Saudi Arabia has made clear it will step in to fill the gap.
