@Mr. Racewar1488 already reported on most of these but I'd like to do a summary + add some footage from Beirut.
Over 100 missiles were launched towards northern Israel by Hezbollah in the beginning of the operation they titled "Operation Devoured Chaff / Windstorm". This was known to the Israeli government the entire day and the information about it had leaked to Israeli media, which was
blocked from reporting on it after bringing it to the Israeli censor beforehand. They were only allowed to publish it after
CNN said the same thing. The barrage had only managed to hit Muslim areas and 2 people are lightly injured,
towns warned their citizens 2 hours prior to stay near their shelters, expecting this to happen.
A senior official told
ynet Wednesday evening: "We are on the eve of opening a broad campaign in Lebanon. We will call up reservists."
The official added: "We knew in advance of their intention to fire a larger volume tonight. There is now a security discussion underway, and the campaign in Lebanon is set to expand significantly. Hezbollah, in its view, wants to divert our attention from Iran and believes that if it pulls us in deeper, we will ease off the campaign against Iran. It wants to create a new equation under which Israeli enforcement policy in Lebanon stops and we do not strike at all. That will not happen. So this entire event is heading toward a serious escalation."
At the same time, Israel sent an explicit threat to Lebanon through Western countries and the United States. According to the message conveyed to Beirut: "If you do not restrain Hezbollah, we will attack national infrastructure. The responsibility lies with the State of Lebanon."
Footage of Israeli strikes on Beirut following a statement by former IDF Arabic spokesperson Avichay Adraee (which is now doing this for the love of the game it seems, or he's taken his job back from Ella Waweya for one last war) telling the residents of the southern suburbs "Following the serious crimes committed by the terrorist Hezbollah, the Defense Army will soon act with great force against its facilities, interests, and combat means.":
