Mediators were trying to salvage diplomacy aimed at ending the Middle East war after US President Donald Trump declared the ceasefire over, with a Qatari delegation in Iran and Tehran's top diplomat travelling to Oman.
An exchange of fire this week rocked an already fragile agreement that was supposed to help pave the way for a permanent end to the conflict, which broke out in late February with massive US-Israeli strikes on Iran.
While there have been no direct talks between Tehran and Washington since last month, Iranian media reported that a delegation from mediator Qatar travelled to Iran on Friday.
The visit follows Trump saying talks would continue, despite previously labelling them "a waste of time".
"The Islamic Republic of Iran has asked us to continue 'talks'. We have agreed to do so, but the United States has stated to them, in no uncertain terms, that the Cease Fire is OVER!" Trump posted on his Truth Social platform.
