Iran has threatened to close the Strait of Hormuz, through which roughly a third of the world’s oil and gas is exported via ships. But the threat may be bluster amid reports today that Iran is seeking to de-escalate the fighting with Israel and statements by President Trump, who said he will not allow the Strait to close.

The conflict between Israel and Iran has forced many countries in the Middle East to close their airspace, as Israeli jets and Iranian exploding drones and missiles fly over their night skies.

Israel has launched a series of strikes against Iran, targeting the country’s nuclear program and other military infrastructure. Iran has launched its own strikes in retaliation.
