The U.N. children's agency warned Wednesday that 20,000 children are trapped in the Iraqi city of Fallujah as coalition-backed Iraqi troops fight to retake the city from ISIS, NBC News reported.
UNICEF said food and medicine are running out and clean water is in short supply.
UNICEF's Iraq representative Peter Hawkins called on all sides to provide safe passage for those wishing to leave the city. The U.N. has already raised concerns that ISIS has been using families as human shields.
Iraqi government troops — backed by air support from the U.S.-led coalition — launched a military operation over a week ago to recapture Fallujah, which has been under ISIS control since 2014.
