Benjamin Netanyahu has accused US college protesters of “lining up with baby burners and rapists”.
Speaking on Fox News, the Israeli prime minister launched a withering attack on those who have joined the wave of pro-Palestinian demonstrations at American campuses.
“They’re lining up with Isis, with al-Qaeda, with these baby murderers, these rapists, these head-choppers,” Mr Netanyahu said.
“We have to protect our future and can our world survive if people go with such moral confusion and moral depravity?
‘We have to defeat evil’
“It’s an indictment of higher education in the West when highly educated people cannot distinguish between right and wrong, and between good and evil.
“Hamas is evil and we have to defeat evil, not protest and demonstrate on behalf of evil.”
In the same interview, Mr Netanyahu rejected calls for a ceasefire in Gaza.
“A ceasefire with Hamas means surrender to Hamas and surrender to terror,” he added.
Senior politicians in Israel have been alarmed by the rising tide of anti-Semitism on US campuses.
