FACTBOX: NATO's Kosovo peace force

(Reuters) - NATO troops came under fire during Serb riots in the ethnically divided town of Mitrovica in northern Kosovo on Monday, in the worst violence in the territory since the Albanian majority declared independence last month.

Some 16,000 NATO-led peacekeepers remain in Kosovo from the 46,000 deployed in June 1999, after NATO's 78-day bombing pushed Serb forces out and halted the killing of ethnic Albanians.
