Khamenei demanded an investigation of the detainees, “and others,” about the alleged assassination plot, an “informed source in Iran” told the Emirati news station.

According to the source, “some of those” detained had invited Khamenei to come and visit the same weapons depot near Tehran where a large blast killed 17 people, among them the head of Iran’s ballistic-missiles program.

Khamenei was invited to visit on Novemeber 12, the same day as the blast, according to the Al Arabiya report.
