Yemeni government forces have launched a counteroffensive against Houthi rebels across multiple front lines, following renewed shelling of Marib city. The attacks on Saturday targeted the Houthis' capabilities and forces along several axes, according to a military spokesman, who described the operation as necessary to protect civilians. The escalation comes after Houthi missile and drone attacks on Thursday killed at least 30 government soldiers and wounded 15 others in the provinces of Hadramout and Marib. The renewed shelling of Marib, a city hosting over two million displaced people, follows an attack on Friday that resulted in civilian casualties. The Houthis claim they are acting on suspicions of coordination between government forces and Saudi Arabia on a broader offensive against Houthi-held territory. Elisabeth Kendall, a Middle East specialist, warns the escalation could tip Yemen back into full-scale conflict, as recent troop movements and clashes indicate all the warning signs are present. The United Nations has called for de-escalation, condemning both Houthi missile attacks and continued strikes on oil tankers in the Red Sea.
