# Negotiating teams from the US and Iran could return to Islamabad in Pakistan this week to resume talks to end the war. Negotiations collapsed last weekend, prompting Washington to impose a blockade on Iranian ports.

A source involved in the talks says both countries could return as early as the end of this week, and a proposal had been shared with Washington and Tehran to resend their delegations.
