Iranian Foreign Minister Mohamed Javad Zarif is to meet several of his European Union counterparts Monday, before the June 30 deadline for an international accord on Tehran's nuclear program.
The final round of talks on the Iranian nuclear program are to begin later in the week.
The French news agency reports an unidentified EU source says the meeting with Britain's Philip Hammond, France's Laurent Fabius and Germany's Frank-Walter Steinmeier will be a political meeting ahead of the final negotiations.
The talks will be held on the sidelines of a full meeting of EU foreign ministers, which will discuss extending sanctions against Russia over the Ukraine conflict and the launch of a naval operation targeting people-traffickers in the Mediterranean.
