The mastermind behind the terror attack in Tehran last week was killed on Saturday by Iranian forces, according to the Iranian government. The attack, which killed 17 people, was claimed by ISIS and targeted the country’s parliament as well as the mausoleum of Iran’s founder, Ayatollah Khomeini. A judiciary official said that seven additional people were arrested, accused of having provided aid to the attackers. Those arrests bring the total to nearly 50 people in the aftermath of the attack.
