The entry of the powerful Iranian proxy into the conflict raises fears of further disruption to the world economy as the armed group has capacity to attack shipping in the Red Sea. The vital shipping route is being used by some tankers as an alternative to the Strait of Hormuz, which Iran has closed with strikes on commercial vessels.
Israel said it was prepared for a “multi-front war" and would strike back. In the United States there have been mass protests against the war, but President Trump has insisted the fight will continue against Iran.
Israel’s assault in Southern Lebanon is continuing, with more than 1,100 civilians reported to have been killed there since the start of recent hostilities.

The Arabic name Bab el Mandab means Gate/Gateway of lamentation/grief/tears. Under the prevailing circumstances of war, this could very well be a very apt name for the strait, methinks! — © Mark Alexander
