Arizona man accused of helping plan cartoon attack now charged with supporting Islamic State

An indictment says an Arizona man already accused of helping plan an attack on a Prophet Muhammad cartoon contest in Texas in the spring also planned to fight with the Islamic State group and inquired about explosives to attack a Super Bowl game.

The indictment released Wednesday charges Abdul Malik Abdul Kareem with conspiracy to provide material support to a foreign terrorist organization.

Prosecutors allege he researched traveling to the Middle East to fight alongside the group and inquired about the types of explosives that would be needed to blow up the stadium in metro Phoenix where the 2015 Super Bowl was held.

Kareem is accused of researching the trip and seeking the pipe bomb information with Elton Simpson and Nadir Soofi, who were killed in a May 3 shootout with police outside the cartoon contest in Garland, Texas.

Kareem's attorney, Daniel Maynard, didn't immediately return a call seeking comment on Thursday.
