Iran fires four ballistic missiles at Riyadh — Saudi capital targeted for first time, debris lands across city, phone alerts issued to residents

Saudi Arabia's Ministry of Defense confirmed on March 18 that its air defenses intercepted and destroyed four ballistic missiles launched toward Riyadh. AFP and Reuters journalists in the city heard loud explosions echoing over the capital as defenses engaged the incoming missiles. Debris from the intercepts landed across the city. Riyadh residents received mobile phone alerts for the first time in the war warning of a hostile aerial threat, underscoring the unprecedented nature of the capital targeting. Previous Iranian strikes on Saudi Arabia had focused on the Eastern Province, air bases, and border areas — not the capital. The attack comes hours after the IRGC issued formal evacuation orders and designated five specific Gulf energy facilities — including Saudi Arabia's SAMREF refinery and Jubail petrochemical complex — as targets in retaliation for the South Pars strike. Targeting Riyadh represents a major escalation of Iran's Saudi campaign, striking the political and economic center of the Kingdom rather than peripheral energy or military infrastructure.
