A meeting between Iran’s foreign minister and senior European diplomats has yielded hopes of further talks but no indication of any immediate concrete breakthrough, a week after the crisis centered on the Iranian nuclear program erupted into war between Israel and Tehran.

The first face-to-face meeting between Western and Iranian officials in the weeklong war concluded after four hours with no sign of an immediate breakthrough.

Hours of talks aimed at de-escalating fighting between Israel and Iran failed to produce a diplomatic breakthrough as the war entered its second week with a fresh round of strikes between the two adversaries.
