On October 6th, local time on October 6th, according to Israel Channel 12, Qatari officials responsible for negotiating with Hamas to mediate the exchange of detainees told the families of the detainees last week that Yahya Sinwar, the leader of the Palestinian Islamic Resistance Movement (Hamas), now only uses pen and paper to communicate and no longer calls them. Qatari officials also said that this was made after a series of assassinations led to the deaths of Hamas and Hezbollah leaders, which also posed a challenge to their mediation work.
