There are a lot of children playing outside in eastern Mosul. They run around the front yards of their houses, chasing each other through the alleyways, as their parents sit on plastic chairs keeping — at most — half an eye on them.
At the al-Kufa boys' school, Mustafa Salem, 13, says this freedom is new. During the 2 1/2 years that ISIS controlled his neighborhood, he was rarely allowed to leave the house.
"It wasn't good, there was no school, nothing," he said.
