Friday was a holiday in Iran, much like Veterans' Day in the US. Every city and town was holding ceremonies, parades, and celebrations honoring those who served, and those who lost their lives, during the 1980s Iran-Iraq War. In the town of Ahvaz, however, these festivities ended in tragedy after four men opened fire on the crowd; indiscriminately gunning down everyone in their path.
The police reacted bravely; but by the time the attackers were subdued, 16 people were killed and around 60 critically injured. 8 more of the injured have since died from their wounds.
It appears that the gunmen were disguised in IRGC uniforms, and had hidden their weapons along the parade route. Preliminary indications are that a Wahhabi/Salafist terror group called Al-Ahvazyah was responsible for this dastardly crime. The terror group is largely comprised of Arab refugees (like the ones in the US and Europe) and are funded by Saudi and other Gulf State regimes.
Around the world, countries have condemned the attack. President Putin was among the first to reach out and offer assistance, followed shortly by the Pakistani Government. Supreme Ayatollah Said Ali Khamenei issued this statement to the people:
The Reagan Administration's policy of isolating Iran and reinstating the Shah made geopolitical sense during the 1980s. Iran's government was unstable and in real danger of falling to a Communist or Soviet-backed group. This would have extended Soviet hegemony in Western Asia from the Mediterranean Sea to the Indus River. It would have been a threat to the oil-rich Gulf States as well as US allies, Israel and Turkey. At the time, this was a far greater threat to world peace than the still-nascent danger of the Wahhabi and Salafist Cults.
