Author Douglas Murray has clashed with The Young Turks founder and host Cenk Uygur over the proportionality of Israel’s offensive in Gaza.

The Hamas-run Gaza Health Ministry claimed at least 20,000 people have been killed in the Gaza Strip since Israel launched its offensive, which was in response to the Hamas attack which killed about 1,200 Israelis.

Sky News Australia host Piers Morgan acted as the mediator as the two guests put forward both their arguments.

Mr Murray accused Mr Uygur of “smearing” the Jewish state with claims Israel is committing genocide.

“None of the stats support that ridiculous claim, it's such a weird smear and a libel of Israel,” Mr Murray said.

Mr Uygur, meanwhile, called for “peace and security” for both Israel and Palestine as he accused the IDF of “indiscriminately” killing Gazans.
