Abbas Araghchi was in Beirut for meetings with Lebanese officials. His visit came three days after Iran launched at least 180 missiles into Israel, the latest in a series of rapidly escalating attacks that threaten to push the Middle East closer to a regionwide war.

Lebanon’s state-run National News Agency said an Israeli airstrike led to the closure of the road near the busy Masnaa Border Crossing, from which tens of thousands of people fleeing war in Lebanon have crossed into Syria over the past two weeks.
