On 18 January 2011, Israel arrested Aleksandar Cvetković, a veteran of the Bosnian Serb Army, after the Bosnian government filed an extradition request. Cvetković had moved to Israel in 2006 and secured citizenship through marriage to an Israeli. He was accused of having personally taken part in the executions of more than 800 men and boys, and initiated use of machine guns to speed up the killings. On 1 August 2011, a Jerusalem court approved Cvetković's extradition, and an appeal was denied in November 2012.
