(UPDATE) SEOUL: Hamas fighters likely fired North Korean weapons during their assault on Israel early this month, a militant video and weapons seized by Israel show despite Pyongyang denying it sells arms to the Palestinian militant group.

South Korean officials, two experts on North Korean arms and an Associated Press (AP) analysis of weapons captured on the battlefield by Israel point toward Hamas using Pyongyang's F-7 rocket-propelled grenade, a shoulder-fired weapon that fighters typically use against armored vehicles.
