by Emmitt Barry, with reporting from Washington D.C. Bureau StaffWASHINGTON (Worthy News) – The U.S. National Counterterrorism Center (NCTC) warned Friday that recent calls by al-Qaeda for attacks against the United States highlight the group’s ongoing threat more than two decades after 9/11. Authorities also warned of potential threats against high-profile targets that draw large crowds, including sporting events and concerts. The document recommended visible law enforcement presence at such gatherings and called for pre-event security briefings. A Department of Homeland Security report released late last year noted that al-Qaeda had “reinvigorated its outreach” to Western audiences and remained committed to striking the United States.
