The targets have been aimed at important installations, so far as I understand, but have inevitably killed civilians. Humans shields may have played a part in this. There may be much to criticise Israel for here, but it doesn’t make it genocide, because intent matters. Otherwise the bombings of Hamburg, Hiroshima, Melitupol, Belgrade, Baghdad etc could be classified as genocide. Civilians died in them.
Also, there has been no solid evidence of Israel bombing those making their way southward yet. Given Hamas have been setting up roadblocks to prevent escape and reportedly setting up IEDs, it’s best to be careful. I know of security experts who have said that footage from one incident used as evidence for this does not look like an airstrike:
There seems to be an deflagration, but no detonation – i.e. no high explosives. It doesn't look like any airstrike I've seen.
