After a sleepless and at times tense night in Islamabad, Iranian and U.S. officials ended their highest-level talks in decades without a breakthrough, but 11 sources familiar with the negotiations ​said dialogue was still alive.

The weekend meeting to resolve the conflict between the U.S. and Iran, held four days after last Tuesday’s (April 7, 2026) ceasefire announcement, was the first direct encounter between U.S. and Iranian officials in more than a decade and the ‌most senior engagement since Iran’s 1979 Islamic Revolution.
