Tens of thousands of children from the Gaza Strip spend at least part of their holidays in special summer camps, arranged around a wide array of activities. Some, organized by the United Nations, offer sports, art and dance classes. Others, laid on by Gaza’s Islamist rulers Hamas, include fun and games, while seeking to reinforce religious values and awareness of the conflict with Israel – a nation which Hamas refuses to recognize. Other centers, including some run by Hamas and the Islamic Jihad, provide military training for youths, providing basic firearms practice, and, more controversially, war games to kidnap pretend Israeli soldiers. Photographer Mohammed Salem documented children at two of these camps. Read Mohammed’s personal account here.
