Serbian police have made the first arrests of people suspected of carrying out the 1995 Srebrenica massacre of Bosnian Muslims, Europe's worst civilian slaughter since World War II.

Altogether, more than 8,000 Bosnian Muslims were killed by Serbs in the Bosnian enclave.

The Serbian authorities have arrested seven men accused of taking part in the slaughter of over 1,000 Muslims at a warehouse on the outskirts of Srebrenica, prosecutors have told the Associated Press.

Serbia has put on trial men who took a group of prisoners away from Srebrenica to be killed.

In 2011, Serbian authorities arrested former Bosnian Serb army chief Ratko Mladic - the mastermind - sending him to an international criminal court in The Hague, Netherlands.

The defence in the trial of Mladic on charges of genocide and crimes against humanity opened in May 2014.

Wednesday's arrests, however, were Serbia's first attempt to bring to justice men who got their hands bloody in Srebrenica.

Each year bones are matched to names and buried in a mass funeral on July 11, the anniversary of the slaughter.
