WASHINGTON, September 12,2016 — There are always elements on the internet that will mourn on a day of happiness and laugh on the day of mourning. On any other day, these anti-social elements would have been ignored like a flock of flies but today they must have stung like a bee to the families of 9/11 victims.

As the United States marked the 15th anniversary of the September 11, 2001 terrorist attacks, al-Qaida and Islamic State sympathizers on social media traded congratulatory messages and promised more attacks against the U.S. homeland.The jihadists used social platforms such as Telegram, Twitter and Google Plus to exchange their celebratory messages and share the anti-Western propaganda on this day. They circulated decorated images of the burning World Trade Center in New York, calling the anniversary an "Eid of happiness."
