"The reservists were preparing explosives to demolish two buildings in central Gaza on Monday when a militant fired a rocket-propelled grenade at a tank nearby, Rear Adm. Daniel Hagari, the chief military spokesperson, said. The blast triggered the explosives, causing both two-story buildings to collapse on the soldiers inside."
This actually shows promising cooperation between both sides; the freedom fighter was just helping them in their efforts!
Also I'm reminded of that scene in Django unchained where Django kills Tarantino's character by shooting his dynamite.
