Leave Gaza? No, but they were instructed to go to the other side of Gaza, and civilian convoys doing just that were bombed. Don't worry though people who were able to flee to the camps were also bombed. As for the people who didn't flee, they were surprisingly bombed.
No but they were told to evacuate their homes in the northern Gaza strip and move to the southern Gaza strip - in 24 hours or less. I think that situation may have been deescalated. Some western governments have started telling Israel to stop some of the war crimes.
