Yemen: Houthis promise to respond to dozens of American and British strikes. “We will respond to escalation with escalation,” said a spokesperson for the Yemeni rebel group.

The Iran-backed Houthis began targeting maritime traffic in the Red Sea in November, saying they were targeting Israel-linked vessels "in solidarity" with Palestinians in the war-ravaged Gaza Strip. The United States responded Friday with retaliatory strikes against elite Iranian forces and pro-Iranian armed groups in Iraq and Syria, but did not strike Iranian territory.
