One of the five was accused of collaborating with Israel since 2008. According to the charges, he passed on information to Israel about the location of tunnels dug by the Izz ad-Din al-Qassam Brigades (Hamas' military wing), as well as the activities and locations of its members.
Another Palestinian was accused of collaborating with the Jewish state since 2000, when he worked at the Erez Border Crossing. He is alleged to have passed information to Israel regarding members of the military wing and where they lived, as well as the locations from which rockets were fired and of Hamas' rocket manufacturing facilities.
A third member of the group was accused of collaborating with Israel starting in 2010, causing harm to senior members of Hamas's military wing with the information he gave Israel.
A fourth member of the group was accused of collaborating with Israel since 2008, giving Israel details of al-Qassam Brigades members and their bases.
The fifth man, who was sentenced to death by firing squad, was convicted of passing information to Israel about the movements of Hamas military wing members, which led Israel to target them.
Another Gazan Palestinian was sentenced on Sunday to ten years in prison for collaborating with Israel.
