A Belgrade court has ordered a 30-day detention for the eight suspects arrested this week for taking part in the 1995 killings in Srebrenica.

The order came as Serbian nationalists accused prosecutors of being anti-Serb.

The Belgrade Higher court said Friday that the suspects must remain in jail amid concerns they may abscond or pressure witnesses. The men were arrested Wednesday and accused of taking part in the massacre of some 1,300 people at the warehouse on the outskirts of Srebrenica.

The arrests marked Serbia's first attempt to deal with the mass executions in Srebrenica — some 8,000 Muslims were killed in what is Europe's sole-labeled crime of genocide since World War II.

A nationalist group has demanded the prosecutors be replaced because of the arrests.
