Quote:A Department of Homeland Security (DHS) spokesman late Saturday labeled a string of shootings in Harrisburg, Pa., targeting police officers a terror attack and used the incident to criticize chain migration.

Tyler Houlton said in a tweet that DHS confirmed that the suspect, 51-year-old Ahmed Amin El-Mofty, benefited from extended family chain migration, which takes place when immigrants in the U.S. sponsor other family members for visas.

“Ahmed Amin El-Mofty was a naturalized U.S. citizen who was admitted to the United States from Egypt on a family-based immigrant visa. El-Mofty was killed yesterday in a shootout after allegedly opening fire and targeting police at multiple locations in Harrisburg, Pennsylvania,” the acting DHS press secretary said. “The long chain of migration that led to the suspect's admission into the United States was initiated years ago by a distant relative of the suspect."

El-Mofty allegedly opened fire on police officers in three different locations in the state's capital on Friday. The FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives were reportedly investigating whether the shootings could be considered an act of terror.
