European and Iranian diplomats have arrived in Istanbul in a renewed effort to resolve the standoff over Tehran's nuclear program. The talks mark the first formal engagement since June's 12-day war between Iran and Israel, a conflict that included U.S. airstrikes on Iranian nuclear facilities and heightened tensions across the region.

Tehran and the European troika (E3) of France, Germany, and Britain have reportedly agreed in principle to resume negotiations over Iran's civilian nuclear program, though critical details regarding timing and location remain unresolved.
