ISIS has hailed 9/11 as a "pivotal moment for Islam" in its first-ever statement on the Twin Towers attrocity.
The terror group made the comments in a hate-filled rant on the 19th anniversary of the attacks in New York.
According to SITE Intelligence Group, who monitor ISIS activity, the group 'celebrated' the day that killed almost 3,000 people in 2001.
They tweeted: "For the first time ISIS has published a statement for the anniversary of 9/11 in its Naba newspaper, celebrating the day as a ‘pivotal moment’ in contemporary Islamic history, while lamenting what Al Qaeda has become: short-sighted in viewing the US as its sole enemy."
ISIS are said to see themselves as the "inheritors" of the 9/11 mission.
The group rose to the height of its power in 2014, when it took control in parts of Syria and Iraq to declare an Islamic 'caliphate'.
The state eventually collapsed and retreated back across the Middle East.
Now the terror cult uses online networking to inspire attacks across the world.
Their statement today comes as Americans and countries across the world commemorate the 9/11 atrocities.
Coronavirus fears will see memorials planned around social distancing safety measures - which means President Donald Trump and Democratic challenger Joe Biden will pay respects at the same memorial without crossing paths.
ISIS have waded in with their hate-filled rhetoric on the pandemic also, calling the disease "God's little soldier" after it has infected around 28 million people worldwide.
Followers of the group have even urged one another to "weaponize" the virus by spreading it to disbelievers.
ISIS propaganda claims the virus represents the "divine punishment of the West" - and terrorists could be plotting atrocities as lockdowns ease across the world.
A global recession could help ISIS recruit new members, security analysts fear.
Following a string of attacks in Iraq and Syria, experts say ISIS is "showing confidence in its ability to increasingly operate in a brazen manner in its former core area".
And the report by the UN Security Council Committee adds that the number of attacks has "increased significantly in early 2020 as compared with the same period in 2019".
