After US President Trump rejected a previous version of the peace proposal, Pakistani mediators expect Iran to submit a revised proposal. Sources familiar with the matter say Iran could respond as early as today, or as late as Friday. The sources also indicated that the delay suggests difficulties in contacting Iran's Supreme Leader Ayatollah Mojtaba Khamenei. The report states that the parties are demonstrating patience in different ways. Pakistani Prime Minister Sharif told his cabinet that the Iranian Foreign Minister, who led the negotiations in Islamabad last weekend, "assured me that he would give me a response." While no specific timetable was given, this public urging of Iran is noteworthy, especially after the White House indicated its patience was wearing thin. (CNN)
