(UNICEF) – Since August 25, Bangladesh has seen an unprecedented arrival of Rohingya refugees fleeing targeted violence and serious human rights abuses in Myanmar’s Rakhine State. To date, more than 609,000 people have crossed the border, at a speed the world has not witnessed in decades. Coupled with the pre-existing refugee population there are now more than 821,000 people in Cox’s Bazar in need of humanitarian assistance; 55% of whom are children. Those who have fled speak of seeing both children and adults killed indiscriminately and women and girls targeted for brutal sexual violence. All are in desperate need of food, medical attention, appropriate shelter, basic hygiene items, and critical social services.
