I haven't seen a number of bombs dropped by the IDF recently, but it was in the thousands last I heard probably in December. Israel also has much heavier munitions and is capable of high accuracy. Independent analysis show that by November 6th, the IDF had dropped at least 500 2,000 pound bombs, causing impact craters larger than 40 feet, in densely populated residential areas.

The heavy munitions, mostly manufactured by the US, can cause high casualty events and can have a lethal fragmentation radius – an area of exposure to injury or death around the target – of up to 365 meters (about 1,198 feet), or the equivalent of 58 soccer fields in area.

Israel dropped hundreds of 2,000-pound bombs on Gaza, analysis shows

Whether or not militants hide in hospitals or ambulances it is abhorrent to attack medical staff and is generally recognized as a war crime. There have been numerous deaths of independent observers, foreign medical staff. More UN aid workers have been killed by the IDF since October than in any other conflict in their history.
