Iranian Supreme Leader Ayatollah Ali Khamenei called on the Palestinians to pursue another intifada against Israel while claiming the Israeli government is a “cancerous tumor” that should be confronted.

“The people of Palestine have no option other than keeping the flames of fighting alight by relying on Allah the Exalted and by relying on their innate capabilities, as they have genuinely done so until today,” Khamenei said, according to a translation of a speech on his website.

“… by Allah’s permission, we will see that this intifada will begin a very important chapter in the history of fighting and that it will inflict another defeat on that usurping regime,” Khamenei said Tuesday, Reuters reported.

Khamenei made the comments during a two-day conference in Tehran attended by delegates from some 80 countries, focusing on Iranian support for the Palestinians amid growing tensions with United States and Israel over its ballistic missile and nuclear program.

The Iranian leader also denounced what he calls “compromise strategies” referring to the two-state solution and instead advocated for “all-out resistance.”

“The Palestinian intifada continues to gallop forward in a thunderous manner so that it can achieve its other goals until the complete liberation of Palestine,” Khamenei added.
