In Iraq, concerns are mounting over the fate of 50,000 civilians trapped in the city of Fallujah, as Iraqi forces fight to reclaim the city from ISIS militants. The Norwegian Refugee Council has warned a “human catastrophe is unfolding,” with civilians caught in the crossfire amid fierce fighting. ISIS seized Fallujah in 2014. A decade earlier, Fallujah was the site of one of the bloodiest chapters for U.S. troops in the Iraq War. The U.S. push to recapture Fallujah involved the extensive use of depleted uranium and white phosphorus, leaving a legacy of birth defects that continues today.
