Serbia has called on the International Court of Justice (ICJ) to declare that Kosovo's declaration of independence in 2008 broke international law.
Serbian representatives outlined their case as the court in The Hague opened hearings on Kosovo's secession. They also argued that Kosovo was "the historical cradle of Serbia and constitutes one of the essential pillars of its identity".
Kosovo is expected to present its view later on Tuesday.
Serbia still considers Kosovo to be part of its territory, and is hoping a favourable ruling at the ICJ will stop it gaining international recognition. Read the whole BBC article here.
