Khazer IDP camp, Iraq - Huda Mahmood Ali's children often ask her why they cannot go to school like the other children.
"They love to go to school, sometimes they go to the classes anyway and the teachers kick them out because they are not registered," she says. "I'm afraid my children have no future."
The 34-year-old mother has tried to explain to her five undocumented children that it is simply because their IDs were lost when they fled their home in July 2017.
"We were running from Mosul, I was carrying the children and lost the bag that had all my documents and IDs in it. I wasn't concentrating on it. Everyone was running," Huda says.
