On September 26, 2014, Alton Nolen attacked two women, decapitating one, at the Vaughan Foods plant in Moore, Oklahoma. In a review of Nolen's Facebook profile, which is listed under the alias "Jah'Keem Yisrael," his first post appears to have been on February 16, 2009, and his last on September 24, 2014.

In response to U.S. airstrikes on Islamic State (IS) and al-Nusra Front-affiliated targets, jihadists flooded social media—particularly Twitter—to condemn the attacks, call for jihadist unity in the region, and issue threats toward the U.S. and allied countries.

The Islamic State (IS) released the first episode in which a British captive, John Cantlie, speaks on the alleged truth about the group that is hidden by the Western media. The 3 minute, 21 second video, entitled, "Lend Me Your Ears: Messages from the British Detainee John Cantlie," was produced by the group's al-Furqan Media Foundation, and distributed on Twitter on September 18, 2014.

On August 16, 2014, al-Qaeda in the Arabian Peninsula (AQAP) released an English-language publication calling for lone wolf jihadi attacks, targeting American, British, and Israeli interests. Among the most striking new elements in the publication, titled "Palestine: Betrayal of the Guilty Conscience," is the introduction of new attack targets for lone wolves in the United States and the United Kingdom within its reissue of AQAP's 2010 car bomb manual, "Make a Bomb in the Kitchen of Your Mom."

Days after launching a campaign to direct threats to the U.S. in the event it intervenes in Iraq against the Islamic State in Iraq and Sham (ISIS), jihadists on Twitter have intensified their efforts, suggesting targets and inciting Muslims to act.
