Iran’s Supreme Leader Ayatollah Ali Khamenei has called on Muslim states to cease oil and food exports to Israel, demanding an end to its bombardment of the Gaza Strip, Reuters reports.

“The bombings on Gaza must stop immediately … the path of oil and food exports to the Zionist regime should be stopped,” Khamenei told a group of students in Tehran, according to Iranian state media.

Khamenei, Iran’s top authority, said the United States was complicit in Israel’s “recent crimes against Palestinians”. “The Islamic world should not forget that in the crucial issue of Gaza, those standing against the oppressed Palestinian nation were the United States, France and Britain,” Khamenei said to chants of “Death to Israel” and “Death to America”.

“One of the shameless acts of the West is accusing Palestinian fighters of terrorism,” Khamenei said.
