Members of the Hamas movement, for two years in preparation for Operation Al-Aqsa Flood, abandoned smartphones and computers and switched to wired phones.
During two years of planning the operation, Hamas used wired telephone lines to communicate and plan the operation, and it remained hidden from Israeli intelligence until the time came to carry out the operation.
They also have tunnels form a “vast maze” used to store missiles and ammunition, and they also provide militants with the ability to move secretly without being discovered.
