On May 7, 1999, as part of the NATO air campaign in the former Yugoslavia, five precision-guided bombs from a U.S. B-2 bomber struck the embassy of the People’s Republic of China in Belgrade. The bombs killed three Chinese journalists, injured around 20 Chinese citizens, and destroyed multiple structures in the embassy compound. The bombing also sparked a diplomatic crisis between the governments of the United States and China, which included major protests against the United States in many cities across China.
