The rocket came from Lebanon and has been widely blamed on Hezbollah, however, the group denied responsibility soon after the mass civilian casualties became evident. Interestingly, Syria blamed an Israeli anti-air rocket for the catastrophe. The Israeli prime minister and his defense minister, Yoav Gallant, have received formal authorization from an emergency security cabinet session Sunday night to retaliate in a way of their choosing against Hezbollah.

Israeli media has on Monday said that Hezbollah has begun moving around its precision-guided missiles while bracing for an imminent major response. Israeli ministers are still signaling it will remain ‘limited’ though other sources have warned that all-out war in Lebanon is coming.
