(Amnesty International) – Children and their families returning home in northern Yemen after a year of conflict are at grave risk of serious injury and death from thousands of unexploded cluster bomb submunitions, Amnesty International said, following a 10-day research trip to Sa’da, Hajjah, and Sana’a governorates. International assistance is urgently needed to clear contaminated areas and countries with influence should urge the Saudi Arabia-led coalition forces to stop using cluster munitions, which are internationally banned and inherently indiscriminate.
