RIYADH: Saudi Arabia condemned and denounced a terrorist attack on a military base in northeastern Jordan that killed three American troops, the Kingdom’s foreign ministry said on Monday. US President Joe Biden said “radical Iran-backed militant groups operating in Syria and Iraq” were behind the strike on the frontier base in Jordan’s northeast. The attack on Sunday was the first deadly strike against US troops since the Israel-Hamas war erupted in October. The ministry reaffirmed the Kingdom’s support for international efforts to eliminate terrorism and extremism in all forms. US Defense Secretary Lloyd Austin on Monday vowed that the US would take “all necessary actions” to defend its troops after the drone attack that killed three US forces and wounded dozens more.
