Due to their status as permanent residents in Israel, they carried Israeli blue identity cards, which allowed them to work in Israel and to easily travel in Israel without being suspected. While the Israeli security forces investigated the incident they found out that the cell members, who were referred to in the media as "The Silwan cell", were responsible for a series of attacks against Israeli civilians, including the attack at Café Moment, which in total killed 35 Israeli civilians and injured 200 others.[4] According to the Israeli security forces the cell operated in accordance with the instructions they received from the Hamas headquarters in Ramallah, which instructed them to locate a crowded public space to carry out a mass-casualty suicide attack.
