Talks between the United States and Iran may restart as early as next week in Islamabad, Pakistan, the Wall Street Journal said in a report, citing sources familiar with the matter.

The report said both sides are working with mediators to draft a one-page, 14-point memorandum of understanding outlining the framework for a month of negotiations aimed at ending hostilities.

The draft is expected to cover Iran’s nuclear programme, methods to ease tensions in the Strait of Hormuz, and options for transferring Iran’s highly enriched uranium to another country. Key issues, however, remain unresolved.

The scope of sanctions relief is still under discussion and could complicate the talks.

If progress is made, the initial one-month negotiation period could be extended by mutual consent, according to the report.

The conflict began on February 28 after the US and Israel launched strikes on Iran.

In response, Tehran conducted retaliatory attacks on regional countries and also imposed a blockade in the Strait of Hormuz, a key waterway for global oil and gas shipments.

A ceasefire, brokered by Pakistan, took effect on April 8, but the first round of talks in Islamabad on April 11 ended without a lasting agreement.

The truce was later extended by President Donald Trump, without a specified end date.

Since April 13, the US has maintained a naval blockade targeting Iranian shipping in the strategic waterway.
