Serbia arrested seven men on Wednesday suspected of taking part in the 1995 Srebrenica massacre in Bosnia, in the first such arrest in Serbia of alleged triggermen in Europe's worst atrocity since World War Two.

"This is the first such case involving people directly suspected of taking part in the Srebrenica massacre... There are other suspects in Serbia and neighboring countries and we are after them as well," Bruno Vekaric, Serbia's deputy war crimes prosecutor, told Reuters.

In July 1995, Bosnian Serb forces killed more than 8,000 Muslim men and boys in the eastern Bosnian enclave of Srebrenica, a designated United Nations 'safe haven'.
