The United States and Iran have now traded strikes for ten consecutive days, with the Pentagon confirming at least 17 American service members killed and 447 injured, including 100 further casualties disclosed only after the Pentagon admitted its reporting had lagged. Amid this escalation, Iran-backed Houthi rebels in Yemen have announced a naval blockade of the Bab el-Mandeb Strait, a vital waterway linking the Red Sea to the Indian Ocean, opening a second front in the disruption of Middle Eastern shipping and energy routes alongside the already-closed Strait of Hormuz.

The Houthis said the blockade was launched in retaliation for Saudi Arabian strikes on a major airport in Sanaa, Yemen's capital. Ship-tracking data already shows two oil tankers rerouting away from the strait, described as the first practical response to the heightened security risk in the Red Sea. Bab el-Mandeb is a crucial export route for Saudi Arabian oil, and with Hormuz effectively shut by the wider U.S.-Iran conflict, the new blockade threatens to further squeeze global energy supplies and push prices upward.
