South Korean protesters scuffle with riot police as they try to block US beef shipments at the southern port of Busan, 450 kilometers southeast of Seoul on June 26, 2008 after the government formally lifted an import ban. South Korea authorised the resumption of US beef imports after winning new safeguards from Washington against mad cow disease. Fears of the disease prompted weeks of mass street protests which shook the government. AFP PHOTO/CHOI JAE-HO
