A former Serb paramilitary has been jailed for 15 years in Croatia for his part in the Srebrenica massacre in Bosnia in 1995.

Slobodan Davidovic was convicted of taking part in the killing of six Bosnian Muslim men, which was captured on a recently discovered video.
Five men are currently being tried in Serbia over the same incident.
Davidovic denies the charges. His lawyer said he intends to appeal against the verdict.
He was arrested in June after being spotted when the video was shown at the trial of Slobodan Milosevic.
"Testimonies and the video of the executions, in which Davidovic was recognised, clearly show that he and the others had taken part in killing the Muslims," said presiding judge Miroslav Sovanj.
The video showed the six captives, their hands tied, being ordered to walk into a wood and then shot.
Davidovic, 52, an ethnic Serb from the Croatian city of Vukovar, was also found guilty of torturing captured Croatian soldiers in 1991.
