 Hamas used North Korean weapons in attack on Israel. Hamas militants have likely used North Korean weapons in their attack on Israel. Associated Press reported this, referring to sources in South Korea experts on North Korean weapons captured by Israel on the battlefield and videos by militants. South Korean officials, two experts on North Korean weapons and an Associated Press analysis of weapons captured by Israel on the battlefield indicated that Hamas was using a Pyongyang-made F-7 grenade launcher, a shoulder-fired weapon that militants typically use against armored vehicles. The evidence shines a light on the murky world of the illicit arms shipments that sanction battered North Korea uses as a way to find 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 Associated Press said. Experts interviewed by the news agency said the F-7s have been observed in Syria, Iraq, Lebanon and the Gaza Strip. The AP reports that the North Korean F-7 resembles the more common Soviet RPG-7 rocket-propelled grenade launcher with a few notable differences. The weapons captured by the Israeli forces and shown to journalists also seem to be the F-7s. During a briefing for journalists, South Korea's Joint Chiefs of Staff mentioned the F-7s as one of the North Korean weapons it believes Hamas used in the attack.
