Saudi Arabia's King Khalid International Airport in Riyadh was struck twice over the weekend by Iran-backed Houthi forces from Yemen, killing a Pakistani national and injuring at least 11 people. The attacks mark an escalation in the wider Iran war, with Tehran's foreign minister separately calling Saudi Arabia's counterpart to urge diplomacy and offering to help broker talks between Riyadh and the Houthis. The strikes come as Iran says the United States has accepted some of its peace terms in related negotiations but has dismissed Washington's reply as 'inadequate.' The repeated attacks on a major civilian airport have heightened regional alarm and underscored the fragility of efforts to de-escalate the broader conflict.
