Israel said that the navy forces "found weapons ready in advance and used against our forces." IDF photos displayed knives, metal and wooden poles, flares, wrenches and slingshots with marble projectiles said to have been used against the soldiers. The activists were said to have also lobbed stun grenades at IDF soldiers, and the IDF showed video illustrating this. The Israeli searches of the ship found bulletproof vests, night-vision goggles, and gas masks. A press-release by the Foreign Affairs Minister of Israel said that violence against the soldiers was already planned, and that "light weaponry" was found on the ships, including pistols that would have been seized from activists on the "Mavi Marmara" by the Israel Defence Forces (IDF) soldiers.
