At least sixteen civilians were injured in an artillery bombing in the southwestern Yemeni city of Taiz, a health and aid organization said on Tuesday.
The bomber struck shortly after noon in front of a house in the main city of Taiz, Médecins sans frontières (MSF) said in a statement.
Among the injured are elderly people, women and children, with three victims under the age of 10, according to the same source. All are being treated at an MSF-supported hospital.
On Monday, the Saudi-backed internationally recognized Yemeni government accused Shiite Houthi rebels of bombing civilian areas, causing casualties.
The two sides have been at loggerheads since late 2014, in a conflict that many observers have described as a mediated war between Saudi Arabia and Iran, the region's two major powers.
The Houthis seized control of the capital Sanaa and much of the north at the time, forcing the government of President Abd Rabbu Mansour al-Hadi to flee to the south.
The conflict escalated as the Houthis continued their advance toward Aden, in the south, the interim government, forcing Saudi Arabia to intervene, leading an alliance of mainly Arab states, in late March 2015.
The ongoing war has brought Yemen to the brink of starvation and has virtually destroyed the country's public health infrastructure, one of the poorest in the world. The UN calls the humanitarian crisis in Yemen the worst in the world.
