The Hamas terror group recruited up to 15,000 new operatives during the recent war with Israel, meaning that the organization has replaced nearly all of the terrorists slain during the conflict.

U.S. Congressional sources, citing intelligence reports, told Reuters that it’s believed Hamas has gained between 10,000 and 15,000 new members.

Notably, the sources say, almost an identical number of Hamas operatives are believed to have been killed in battle against the Israeli military.
