Garland, Texas

A far-right politician, who gave a speech at a Dallas area event attacked last month for featuring a Muhammad drawing contest, said the images will be aired on Wednesday.

In a bulletin, the self-declared Islamic State said the two suspects were "soldiers from the soldiers of the Caliphate." U.S. officials said they were investigating a link to international terrorism.

The men, police said, fired assault rifles as soon as they came out of their vehicle. One police officer fired back and killed both suspects. Police say they have not ruled out terrorism.
