ICJ to rule on legality of Kosovo's independence
22 July 2010 Last updated at 10:34 BST
The International Court of Justice is due to deliver its opinion on whether Kosovo's declaration of independence from Serbia in 2008 was legal.
The secession, by Kosovo's ethnic Albanian majority, came after the Kosovan war between Serb forces and Albanian separatists, which ended when NATO bombed Serbia and Montenegro.
If the ICJ sides with Serbia, Kosovo could be pushed into negotiating a settlement. The opposite could see more countries recognising its independence.
