On July 3, 2015, Ibrahim Abdulkareem's home was hit by a Saudi airstrike, with his family inside. "It was 1:30 in the morning," Ibrahim writes in Arabic, "we were sleeping."

Ibrahim, the father of two, awoke to the sound of his wife screaming. She was pinned under the rubble of their collapsed walls. His son appeared to be OK. But his young daughter was completely buried in plaster and stone. EMTs arrived and they dug her out. The girl, her brother, and their mother were rushed to area hospitals.

Ibrahim's experience is not unique — six children were injured or killed every day in the first year of Yemen's civil war, according to UNICEF.

In March 2015, a Saudi-led coalition of mostly Arab nations sought to restore the government of Yemeni president Abdrabbuh Mansour Hadi, who had fled to Riyadh. The coalition began bombing areas controlled by the rebel group that had sidelined him, known as the Houthis. While representatives of the warring sides seek a diplomatic solution, fighting continues in many parts of the country, and civilians continue to die.

A United Nations-funded panel recently documented 119 cases in which the Saudi-led coalition killed Yemeni civilians with bombs and missiles. Additionally, a new UNICEF report reveals that over 900 children were killed and more than 1,300 injured during the first year of fighting by both sides in the Yemen war.
