(ABC News) – During a recent trip back to the outskirts of his hometown of Raqqa, Abu Ismail saw that life in the city, which over the past few years has become the de-facto capital of ISIS in Syria, is now nothing like it was when he left in 2013. Abu Ismail, 54, was told by residents who had just fled the predominantly Sunni city that they had no clean water inside – instead, they had to drink unsanitary water from wells. Some went without food for days, while others boiled grape leaves and had the soup for dinner. The lack of nutrition and clean water is making many civilians sick, while some sustain injuries from bullets and explosions in the beleaguered city — and all have little or no access to healthcare, he said.
