Simon Harris, who is set to become Ireland’s youngest ever prime minister, has denounced Israel’s war conducts in the Gaza Strip.

"What we've seen happen in Gaza and the actions of the Israeli government, is utterly reprehensible. It's appalling and it's grotesque,” he told Sky News. 

He added, "And we are seeing children being maimed and killed - innocent children. It is disgusting. It is despicable. And it must stop."

Harris said Ireland "will always speak truth to power", and calls for "an immediate ceasefire".

"The attack on aid workers was particularly, in my view, callous and chilling, and we will continue to call that out. We also, as a country, stand ready to play our part in a political process that brings about a two-state solution," he noted.
