Kosovo War: Three Chinese citizens are killed and 20 wounded when a NATO aircraft inadvertently bombs the Chinese embassy in Belgrade, Serbia.

The Kosovo War was an armed conflict in Kosovo that lasted from 28 February 1998 until 11 June 1999. It was fought between the forces of the Federal Republic of Yugoslavia (FRY), which controlled Kosovo before the war, and the Kosovo Albanian separatist militia known as the Kosovo Liberation Army (KLA). The conflict ended when the North Atlantic Treaty Organization (NATO) intervened by beginning air strikes in March 1999 which resulted in Yugoslav forces withdrawing from Kosovo.

The North Atlantic Treaty Organization, also called the North Atlantic Alliance, is an intergovernmental military alliance between 32 member states—30 in Europe and 2 in North America. Founded in the aftermath of World War II, NATO was established with the signing of the North Atlantic Treaty in 1949. The organization serves as a system of collective security, whereby its independent member states agree to mutual defence in response to an attack by any external party. This is enshrined in Article 5 of the treaty, which states that an armed attack against one member shall be considered an attack against them all.

On May 7, 1999, during the NATO bombing of Yugoslavia, five U.S. Joint Direct Attack Munition guided bombs hit the People's Republic of China embassy in Belgrade, Serbia, killing three Chinese journalists and outraging the Chinese public. According to the U.S. government, the intention had been to bomb the nearby Yugoslav Federal Directorate for Supply and Procurement (FDSP). President Bill Clinton apologized for the bombing, stating it was an accident. Central Intelligence Agency (CIA) Director George Tenet testified before a congressional committee that the bombing was the only one in the campaign organized and directed by his agency, and that the CIA had identified the wrong coordinates for a Yugoslav military target on the same street. The Chinese government issued a statement on the day of the bombing, calling it a "barbarian act".
