Israeli Prime Minister Benjamin Netanyahu has said Hamas is the "enemy of civilisation" and will be "crushed".
The Israel-Hamas conflict has seen over 1300 Israelis killed so far and more than 1200 Palestinians - while 17 British nationals are feared dead or missing.
The BBC has rejected criticism over its decision not to call Hamas militants “terrorists” after it was labelled “disgraceful” by the Defence Secretary.
Douglas Murray says the celebration of the Hamas attacks shows there are "simple supporters of genocide” in the UK.
“Sometimes a flare goes up and you see exactly where everyone is. These antisemites, racists, genocidists are all in plain view.”
Talking to Julia Hartley-Brewer, the author also calls for open supporters and leaders of Hamas in the UK to be arrested.
“If they wish to live in the Gaza they should do, they can take their chances there. Britain doesn't want or need them - bye bye!”
