Gunmen terrorized Texas and ISIS warns for more attacks to come

More questions are raising on the possibility of a homegrown terror plot as authority are digging into the depths of the attack on Sunday.

The air in Garland, a suburb of Dallas, encountered severe shootout on Sunday as two heavily armed gunmen named Nadir Soofi and Elton Simpson faced came face to face with police blocking their way into a cartoon exhibit depicting the prophet Muhammad.

They drove up to the building where the contest was being held and open fired on the police who were on duty outside. They exchanged several rounds of fire before an unarmed school district security guard took a shot in the ankle and after a fight lasting a bit more than 15 seconds a police officer finally succeeded in killing them both.

Early in 2011, the 30-year-old Elton Simpson was convicted of falsifying on his involvement in international and domestic terrorism for which he was sentenced to three years of probation.

However, Soofi, the second gunman, is relatively unknown to federal investigators of having any criminal Involvement in the past.

Just prior to the attack, Simpson threatened on a tweet with the hashtag #texasattack: “May Allah accept us as mujahideen.”

The tweet also stated that he and Soofi had taken solemn oaths to “Amirul Mu’mineen,” dubbed as “the leader of the faithful, analysts are claiming that it is likely referring to the ISIS leader Abu Bakr al Baghdadi”.

Although the motive for the late Sunday attack was not immediately clear, but on Tuesday ISIS’s Al Bayan radio station, located in Raqqa, Syria has claimed to be responsible for the attack. The group stated that two of Al Khilafa soldiers attacked the event. Al Khilafa is how ISIS refers to its soldiers.

The message broadcast said, “We tell America that what is coming is more bitter and harder and you will see from the soldiers of the Caliphate what harms you.”

This is the first time ISIS has claimed responsibility of an attack on U.S. land, but analysts are suspicious that the group’s claim was an opportunistic co-opting of a so-called “lone wolf” attack as one of their own.
