Meanwhile, in Syria, thousands of residents continued to flee Raqqa as U.S.-backed militias intensified their assault on the ISIS-held city. On Wednesday, escaping civilians arrived at an open-air relief camp outside Raqqa complaining of constant airstrikes, artillery raids and extreme hunger.

Djazia: “We left because of the fighting. We were afraid. We have children. We almost died of hunger, and no one helped us.”

Oubayd: “We are displaced now, and we live in the open air. These are our house belongings. We just managed to get them today. This is what we have. These are the last things we owned in the house.”

Some 200,000 people have been displaced from Raqqa, with more expected to flee as fighting intensifies. U.S.-led airstrikes have killed hundreds of residents, in what U.N. investigators have called a “staggering loss of civilian life.”
