2017 Tehran attacks

A series of two simultaneous terrorist attacks were carried out on 7 June 2017 by five terrorists belonging to the Islamic State of Iraq and the Levant (ISIL) against the Iranian Parliament building and the Mausoleum of Ruhollah Khomeini, both in Tehran, Iran, leaving 17 civilians dead and 43 wounded. The shootings were the first terrorist attacks in Tehran in more than a decade, and the first major terror attack in the country since the 2010 Zahedan bombings.

Government officials later stated that they had foiled a third attack that day. Iranian security services stated on 8 June that they had identified the five militants responsible for the twin events, disclosing the men's first names, and detailed that they were of Kurdish Iranian background and had returned to Iran in August 2016. The terrorists reportedly served in a clandestine cell linked to Wahhabi-related networks. Some Iranian officials have accused the American, Israeli, and Saudi governments of being behind the attacks.

On 13 June, the Commander of Iran's Islamic Revolutionary Guard Corps (IRGC), Major General Mohammad Ali Jafari, stated that the terrorist attacks were carried out at the demand of Riyadh. "We have precise intelligence showing that unfortunately, Saudi Arabia, in addition to supporting the terrorists, has demanded them to conduct operations in Iran," he said.

The formal state funeral took place on 9 June in the context of traditional Friday prayers, and multiple Iranian officials attended such as President Hassan Rouhani, Parliament Speaker Ali Larijani, and Chief Justice Sadeq Larijani. Rouhani's speech stressed national unity, saying that "the nation will undoubtedly emerge victorious". On 10 June, security officials stated that they had killed the operational commander and mastermind behind the attacks.

On 18 June 2017, the IRGC launched a series of medium-range precision missiles at an ISIL headquarters in Dayr al-Zawr (Syria) from inside Iran. The retaliatory strikes were, according to an IRGC statement, sending a message to the terrorists and their networks of supporters after the bloodshed in Tehran.
