Why is Israel still bombing Gaza?

There is no question that Hamas in Gaza is and will continue to violate the ceasefire agreed under the Trump three-phase deal. Israel has evidence that Hamas gunmen are carrying out activities that breach the conditions. However, why does the Israeli government feel it is necessary each time it spots a Hamas gunman emerging from an underground bunker to launch deadly airstrikes which kill a lot of people, gunmen and civilians. The strikes today have killed 28 people in Gaza, according to the Hamas-run health ministry in the territory. The figure is horrific, adding to the 73,000 Palestinians killed since the Israel Defence Forces launched strikes on Gaza following the massacre by Hamas on October 7 2023. Normally one would expect Hamas to exaggerate the death toll. But an Israeli official has now confirmed the Hamas figure of around 73,000. So 28 people probably did die today in the latest Israeli bombing raids. Collateral damage - that dreadful phrase - has been a huge factor in the war in Gaza. Women and children in their thousands have been killed. Hamas had no compunction about killing or kidnapping women, young or old. But Israel is a sophisticated military power with tremendous intelligence capabilities. So why are women and children in Gaza still being killed in what is supposed to be an official, internationally-recognised and mandated ceasefire?
