The evidence shines a light on the murky world of the illicit arms shipments that sanction-battered North Korea uses as a way to fund its own conventional and nuclear weapons programs.

Rocket-propelled grenade launchers fire a single warhead and can be quickly reloaded, making them valuable weapons for guerrilla forces in running skirmishes with heavy vehicles.

Hamas has published images of their fighters with a launcher with a rocket-propelled grenade with a distinctive red stripe across its warhead, and other design elements matching the F-7, said Matt Schroeder, a senior researcher with Small Arms Survey who wrote a guide to Pyongyang’s light weapons.

In a background briefing with journalists Tuesday, South Korea’s Joint Chiefs of Staff specifically identified the F-7 as one of the North Korean weapons it believed Hamas used in the attack.

However, Pyongyang last week through its state-run KCNA news agency dismissed claims that Hamas used its weapons as “a groundless and false rumor” orchestrated by the United States.
