SANAA: An attack by the Houthi militia on a residential area in Yemen's Taiz province resulted in injuries to a total of 13 children, a security official said. The official said that the Houthis had recently been firing mortar shells at random into a neighbourhood with many homes in Taiz's southwest. The shells that fell randomly on the government-controlled residential area resulted in injuries to a total of 13 youngsters, he claimed. The incident took place as a high-ranking UN team arrived in Taiz, Yemen's third-largest city, to urge the country's warring parties to extend the cease-fire, which expires on August 2. In recent days, Yemen's Houthis have launched a number of raids against different regions of the war-torn Arab nation, even as UN Special Envoy for Yemen Hans Grundberg has intensified his efforts to prolong the Yemeni ceasefire. Under the supervision of the United Nations, the government and the Houthis engaged in a number of rounds of negotiations, but no progress was made toward putting an end to Yemen's protracted military struggle. The United Nations request to extend the cease-fire with the Saudi Arabia-led coalition for another six months was met with fresh requirements by the Houthi militia, which is supported by Iran.
