ISIS jihadists tweeted about the Texas attack beforehand

Breaking news from Fox:

A pair of social media accounts possibly linked to the Islamic State terror group posted messages referencing Sunday evening's attack on a Texas free speech event moments before it happened.

The Los Angeles Times reported that a Twitter account bearing the name "Shariah is Light" posted a message with the hashtag "texasattack" at 6:35 p.m. Central Time. The account featured an image of Anwar Awlaki, an American-born cleric killed in 2011 by a drone strike in Yemen.

Moments later, authorities say two men pulled up in a car to the Curtis Culwell Center in the Dallas suburb of Garland, Texas and opened fire. A school security guard was injured in the ankle before police officers shot and killed both suspects. The gunmen had not been identified as of Monday morning and their bodies lay next to their car while police searched for a possible incendiary device.

Authorities have not officially determined whether the shooting was linked to an event, a contest hosted by the New York-based American Freedom Defense Initiative that would award $10,000 for the best cartoon depicting the Muslim prophet Muhammad.

"Shariah is Light" also tweeted a command to follow a second account, titled "AbuHussainAlBritani". That second account posted several messages referencing the shooting in Texas and appearing to link it to the Islamic State, also known as ISIS.

"The knives have been sharpened, soon we will come to your streets with death and slaughter!" the first message from the account read.

A second message said "Allahu Akbar!!!!! 2 of our brothers just opened fire at the Prophet Muhammad art exhibition in texas!"

“Kill Those That Insult The Prophet,” a third message said.

A final message from the account read, "They Thought They Was Safe In Texas From The Soldiers of The Islamic State."

Both accounts have been suspended by Twitter.

Breitbart adds:

Approximately twenty minutes before a shooting at an event to promote free speech in Garland, Texas, which resulted in an injured officer and two dead suspects, a radical jihadist account on Twitter posted that a person was with another individual and insinuated that he was planning to sacrifice his life to Islam’s “Allah,” using the hashtag #texasattack.

The bro with me and myself have given bay’ah to Amirul Mu’mineen. May Allah accept us as mujahideen. Make dua #texasattack

The Twitter account of the individual in question, @atawaakul, sports the username, “Shariah Is Life,” and has expressed many pro-Islamic State sentiments on its timeline. A photo of Anwar Al Awlaki, the deceased Al Qaeda master recruiter, is displayed as the Twitter user’s profile picture. On April 23, the Twitter user linked to a Breitbart News article written by Pamela Geller, who organized the “Draw Muhammad Contest” in Garland. Texas.
