Vietnam arrests three including Norwegian and Australian citizens on terrorism charges

Vietnam's Ministry of Public Security announced the arrest of Australian citizen Ho Pham Hiep Huy, Norwegian citizen Nguyen Duc Thuan, and Thai Cong Truong Son on September 18, 2026, on terrorism and forgery charges. While Hanoi claims the men were caught illegally crossing the border from Cambodia with forged documents, pro-democracy group Viet Tan alleges Vietnamese authorities abducted Huy and Thuan in Cambodia in an act of transnational repression. Families of the men have appealed to the United Nations.
