Each faction proudly displays its colors. Hamas, the Islamist group that seized control of the territory in 2007, hands out green caps to kids that attend its sessions; the U.N. Relief and Works Agency dispenses blue-and-white hats; and girls at the Ministry of Endowments and Religious Affairs camps sport white headscarves.
The UNRWA Summer Games camps are by far the best-funded and most heavily attended, catering to more than 250,000 children. But UNRWA has paid a price for its success. Twice in the last month and a half, masked men have attacked the international-aid agency's beach campsites. Mobs burned camps, slashed trampolines and water slides, and left threatening notes with tied-up security guards.
"This is one of the most successful seasons for UNRWA Summer Games; maybe that's what angered others and led them to attack," says Adnan Abu Hasna, Gaza's UNRWA spokesman. Crime is rare in Gaza, where an armed Hamas policeman patrols almost every corner.
The rhetoric used against the United Nations by rival camp organizers is subtle. "The U.N. camps are concentrating only on entertainment. Children go to the beach and play and sing and dance. Ministry camps concentrate on entertainment and memorizing the Quran, which is part of our culture," says Kefh El Ramly, director of the girl's programming at the Ministry of Endowment and Religious Affairs, which is a branch of the Hamas-controlled government.
The ministry runs mosque-based camps for 10,000 children for five hours a day, six days a week. "We teach children to read the Quran, because it is our holy book. We learn a lot from it—manners, how to be good, how to deal with people, how to deal with God, how to deal with our neighbors. It is full of principles and good manners," says El Ramly, who makes no secret of the ministry's desire to Islamize young minds.
Hamas is also blunt about its programming—teaching children to sympathize with the group's ideology. "Major movement leaders come and meet the children. Children here feel they're closer to the movement [afterward], because they feel that someone cares about them," Kamal El Gazi, eastern Gaza Hamas camp organizer, told me.
El Gazi estimates that 50,000 children attend Hamas camps. "We try to grow the seeds of nationalism and Islam in the heart of these children. There are so many activities here related to our culture, not brought in from outside," he says.
The verbal attacks on UNRWA began a few months ago. Although UNRWA normally works solely with refugees, last year they opened up camp attendance to others. As a result, "Hamas thought … that would leave them with no one," says Mkhaimar Abusada, assistant professor of political science at Al-Azhar University in Gaza City. "So this year Hamas started a war of incitement against UNRWA."
As Abusada describes it, leaflets were distributed in mosques across the strip in May and June, claiming UNRWA camps were not serving the "interests" of the Palestinians. Posters touting Hamas' "purposeful" summer camps encouraged parents to enroll their children in Hamas and Ministry of Endowments and Religious Affairs camps.
In some cases, it worked. At one Hamas campsite in Gaza City, boys in green baseball caps and Hamas T-shirts spend their days playing sports and taking classes in subjects like drawing, religion, and culture from Hamas volunteers.
"They can call it summer camps, but in reality this is just part of Islamic socialization. This is just recruiting and political socialization to join Hamas," says Abusada. "They are recruiting these kids to join the al-Qassam Brigades [Hamas' military wing]. Whenever there is a fight with Israel or there is a new round of violence with Israel, most of the boys will be recruited to fight as suicide bombers or at least to join the Palestinian resistance."
