Reuters: Pakistan has sent the United States a revised Iranian proposal to end the war.

Reuters quoted an unnamed Pakistani source on Monday as saying that Islamabad had sent a revised Iranian proposal to end the war to the United States on Sunday night, at a time when talks between the two sides appeared to be still stalled.
When asked whether the disagreements between the two sides would take time to resolve, the source added, “We don’t have much time,” noting that the two countries “continue to change their terms.”
Iran announced on Monday that it had responded to a new US proposal aimed at ending the war, saying that communication with the United States was continuing despite Iranian media reports describing Washington's demands as excessive.
“As we announced yesterday, our concerns have been conveyed to the American side,” Iranian Foreign Ministry spokesman Ismail Baghaei said during a press conference.
He added that communication with Washington “continues through the Pakistani mediator,” without going into details.
