TEHRAN -- Iran's supreme leader Ayatollah Ali Khamenei on Friday called on Arab states to launch a "symbolic" one-month oil embargo against Western countries to pressure them to stop supporting Israel, according to a Reuters report.

"Arab governments can use oil as a weapon. They can cut off the flow of oil to all the countries which have good ties with Israel," Khamenei said in a sermon during the Muslim Friday prayers in Tehran. "I am not saying to cut it forever, just for one month in a symbolic way. If they [Western countries] do not receive oil, their factories will come to a halt. This will shake the world."
