Twin attacks rocked Tehran on June 7 as the Islamic State evidently made a rare foray into Iran. The incidents began around 10:30 a.m. local time, when what appeared to be four gunmen, reportedly dressed as women, opened fire inside Iran's parliament building, killing at least seven people in the initial assault. A small number of family members of Iranian lawmakers were believed to have been taken hostage, and one assailant later reportedly detonated a suicide vest in the upper floors of the building. Around 3:45 p.m., Iranian state media reported that all of the parliament attackers had been killed.
