Iran’s chief of the Cyber War Headquarters, Mojtaba Ahmadi, is the latest person said to be killed in a string of murders targeting the country’s nuclear scientists and security bosses.

Ahmadi was said to be found dead with two bullet wounds near his heart in the outskirts of a town near the capital Tehran, according to the Telegraph.

While the details are still forthcoming, the Telegraph reports that the Iranian government claims outside forces committed the alleged assassination. The government alleges it was most likely done by Israel’s external intelligence agency, the Mossad.
