Rockets fired by Yemen's Houthi 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 Houthi fighters.
The conflict has left nearly 10,000 people dead and more than 55,000 wounded, according to the World Health Organization.
More than 2,200 others have died from cholera and millions are on the verge of famine in what the United Nations says is the world's gravest humanitarian crisis.
