An Arab newspaper reports from "private" sources how the senior Hamas leadership in the Gaza Strip continues to communicate with Hamas and Arab officials while it is deep underground.
According to the newspaper, since 2009, Hamas engineers have begun constructing landline exchanges using equipment smuggled through the Rafah tunnels. These exchanges were set up, among other things, in tunnels.
Over the years this internal communication system has been upgraded.
Although Hamas teams would scan the lines with high frequency, according to the newspaper's sources, Israel managed to penetrate the system in 2018, but when Hamas engineers discovered this in the center of the Gaza Strip, an explosion occurred that killed several of them.
According to the newspaper, during the current war Israel succeeded in destroying a significant part of this system and now the Hamas leadership has returned to primitive means to communicate with the outside world.
This happens through messages written on paper that are delivered from the tunnels by "messengers" close to Hamas to contacts in the Strip who deliver the messages to the Hamas leadership abroad.
