Ibrahim Hussein Abu Naja was one of the commanders of the engineering corps of the Al-Qassam Brigades. He worked to neutralize the occupation’s shells and missiles that it fired at the Gaza Strip.
He was martyred in 2017 by an accidental explosion during preparation and processing at a Qassam site in Rafah. His house formed the first nucleus for manufacturing weapons for the benefit of the resistance. He has a prominent role in developing local weapons manufactured over a period of about 17 years.
