WASHINGTON (AP) — The U.S. has bolstered defenses at a base in Jordan that was attacked by Iran-backed militants as it prepares for a wider U.S. response to a drone attack that killed three service members, a U.S. official said Friday. Even as a larger U.S. military response seemed imminent, some Iran-backed factions pledged to continue to attack U.S. forces in the region. A second U.S. official confirmed the military had taken self-defense strikes inside Yemen against Houthi military targets deemed an imminent threat. The U.S. options under consideration include targets in Syria, Yemen and Iraq, where the Iranian-made drone that killed the service members was fired from, the official said. The U.S. has blamed the Jordan attack on the Islamic Resistance in Iraq, a coalition of Iranian-backed militias.
