ISLAMABAD - US and Iranian negotiating teams could return here later this week for further talks, Reuters quoted multiple sources as saying on Tuesday, after the two sides ended their latest round without a breakthrough.

US officials told the Associated Press that Islamabad and Geneva have been considered as possible venues for the new round of US-Iran negotiations.

Disputes over Iran's nuclear program persist, with Washington pressing Tehran to freeze uranium enrichment and give up its stockpile of highly enriched uranium, while Iran is seeking the release of frozen funds and broader sanctions relief.

Meanwhile, the United States has imposed a naval blockade on Iranian ports, and US President Donald Trump warned that US forces would "eliminate" any Iranian vessel approaching the blockade in the Strait of Hormuz.

Mediators from Pakistan, Egypt and Türkiye are working to revive negotiations before the current ceasefire expires, according to reports.

"We are not in a complete deadlock. The door is not closed yet. Both sides are bargaining. It's a bazaar," a regional source told Axios, a US online media outlet.
