Rockets fired by Yemen's Huthi rebels killed five people and wounded 18 early Tuesday as they struck a residential area in government stronghold Marib, medical sources said. State-run news agency Saba gave the same death toll, but reported that 22 people were wounded in unguided rocket strikes it blamed on the Iran-allied rebels. The war in Yemen pitches the internationally recognised government of Abedrabbo Mansour Hadi and a Saudi-led coalition against the Huthi fighters.
