Iran's warning to block the Bab el-Mandeb Strait endangers global trade, as 5% of the world's oil passes through this critical Red Sea chokepoint.

Iran and its allies may be eyeing the Bab Al Mandab Strait after Hormuz, raising fears of a second maritime front and fresh risks to global trade and energy flows.
