On December 2, 2015, an Islamic terrorist attack, consisting of a mass shooting and an attempted bombing, occurred at the Inland Regional Center in San Bernardino, California, United States. The perpetrators, Syed Rizwan Farook and Tashfeen Malik, a married couple living in the city of Redlands, targeted a San Bernardino County Department of Public Health training event and Christmas party of about 80 employees in a rented banquet room. Fourteen people were killed and 22 others were seriously injured. Farook was a Muslim and an American-born citizen of Pakistani descent, who worked as a health department employee. Malik was a Muslim and Pakistani-born green card holder. After the shooting, the couple fled in a rented Ford Expedition SUV. Four hours later, police pursued their vehicle and killed them in a shootout, which also left two officers injured.
