Omar Shehada, a 35-year-old Palestinian individual on a terror watchlist, was arrested at the southern U.S. border in Santa Teresa, New Mexico, after traveling through several countries to reach the U.S. His capture follows the apprehension of three other Palestinians with potential terrorist ties in California last month. Border Patrol had previously issued warnings about the possibility of Palestinian terrorists attempting to enter the U.S. amid rising tensions from the Israel-Hamas conflict. Shehada is noted for past convictions involving explosives and firearms and remains in custody as he faces deportation. The arrests have raised concerns about how many more individuals with terrorist connections may have slipped through undetected. Lawmakers have called for more stringent security measures in response to these incidents.
