Hamas has developed its domestic production capacity, in part by recycling remains from previous Israeli attacks. Senior officials in the political and military arms of Hamas assure that the majority of weapons at its disposal are locally produced.

A significant number of the weapons used by Hamas's armed wing in combat come from stockpiles stolen from Israeli army military bases that are then smuggled into Gaza or West Bank. “Some [Hamas] weapons come from smuggling, but many have been manufactured locally,” estimates Gazan writer and analyst Ahmed Fouad Alkhatib.
