Qatar said on Tuesday that both the United States and Iran remained committed to mediation efforts and were reviewing proposals put forward by mediators. While the Qatari team that travelled to Tehran had since returned to Doha, talks were continuing, Qatar's foreign ministry spokesperson Majed Al Ansari said.
"There are intensive joint regional efforts underway to avoid escalation," he told a news briefing, adding that Qatar remained hopeful a deal could still be reached to pave the way for future negotiations.
