Palestinian students take part in a military-style graduation ceremony in Rafah in the southern Gaza Strip on March 28.

The military-style exercise in the 138 Hamas-run high schools in Gaza was part of a program sanctioned by the Hamas Islamist government. Education officials in Gaza say some 6,000 students have joined the training initiative where only boys can sign up for the voluntary program and they need their parents' permission to join.
