Al Qaeda Remains Most Dangerous Terrorist Group 24 Years After 9/11

In the 24-years since a group of 19 members of the al Qaeda terrorist group boarded and hijacked four flights in a series of attacks on the U.S. that killed 2,977 people, the infamous network remains the "most dangerous terrorist group" in the world today, warned one expert.

Though terrorist groups like ISIS and Hamas have gained immense notoriety over the last several years due to their brutal tactics, Bill Roggio, expert analyst and senior editor of Foundation for Defense of Democracies’ "Long War Journal," explained to Fox News Digital that the threat posed by al Qaeda is far more sweeping today.

"The most dangerous terrorist group 24 years after 9/11 remains al Qaeda," Roggio said. "With the support of the Taliban, the situation there is far worse than it was pre-9/11."
