On 10 June 1999, then NATO Secretary General Javier Solana had issued the order for ending airstrikes of Serbian forces and the UN Security Council adopted resolution 1244 which enabled deployment of 37,200 KFOR troops from 36 countries. Solana’s decision came after the signing of the Kumanovo agreement between NATO and then Yugoslavia on 9 June 1999 which then entered into force on 11 June 1999. KFOR was split into five areas of responsibility: American, British, French, German, and Italian. Upon NATO’s entry to Kosovo, the UN interim mission also began to settle in Kosovo and would administer it for a certain period.  At the same time, the Kosovo Liberation Army was disarmed and transformed into Kosovo Protection Corps. Resolution 1244 is still in force in certain cases, such as for functioning of UNMIK whose representatives report to the Security Council on the situation in Kosovo every three months.
