US President Joe Biden on Tuesday hailed the "historic" confirmation by a UN court of Bosnian Serb military chief Ratko Mladic's life sentence for genocide in the 1995 Srebrenica massacre. "This historic judgment shows that those who commit horrific crimes will be held accountable," Biden said in a statement. "It also reinforces our shared resolve to prevent future atrocities from occurring anywhere in the world." "My thoughts today are with all the surviving families of the many victims of Mladic's atrocities. We can never erase the tragedy of their deaths, but I hope today's judgment provides some solace to all those who are grieving." sms/jm
