The strikes came after militants targeted Israeli forces "almost immediately," Israeli Defense Ministry spokesman Peter Lerner said."
Note how the construction of these sentences implies that Israel broke the creasefire. Three hours into it, "Isreali forces fired at militants in the Hamas-ruled...territory." THEN the article says that Hamas struck first. Here's how I would have worded the same idea:
"Only minutes after the three-hour truce was set to begin, Israel responded to an attack made by Palestinian militants."
I think the qualification of self-defense is a crucial point that many media (and government) sources are failing to make. If we agree not to fight and you hit me, YOU broke the agreement, not I when I hit you back.
