Serbian nationalist leader Vojislav Seselj looks on during a news conference inside his Serbian Radical Party headquarters in Belgrade, April 2, 2015. A Serbian ultra-nationalist freed on compassionate grounds by a United Nations war crimes court, then ordered to return for violating the terms of his release, thumbed his nose at the court on Wednesday by setting fire to a Croatian flag. Seselj, who has cancer and was freed in November, repeated that he would not voluntarily return to the tribunal for the former Yugoslavia in The Hague, which revoked his release order on Monday.
