US and Iran conclude high-level talks in Switzerland, mediators say

The first round of talks between high-ranking U.S. and Iranian officials in Switzerland ended Monday, mediators said, after a tense opening marked by ​Tehran's announcement it had again closed the Strait of Hormuz and U.S. President Donald Trump repeating his threats to resume attacks on Iran, Reuters reported. 

A joint statement from mediating nations Qatar and Pakistan said the ‌U.S. and Iran agreed to a roadmap toward a final deal within 60 days.

Technical talks will continue for the rest of the week in the Qatari-owned Swiss mountain resort of Buergenstock, according to the statement, which was released by the Qatari foreign ministry.
