A retired Irish Army Colonel who gave evidence in the trial of Serbian General Ratko Mladic in The Hague has said there are fears that the hatred seen in Serbia in the 90s could "resurrect itself."

Colm Doyle's evidence was based on his role as Head of the European Union Monitoring Mission in Bosnia from October 1991 to April 1992.

Speaking on RTÉ's News at One, Mr Doyle said he does not think the unities within Bosnia are working.

He said there has been no reconciliation in that part of the world.

There is still a belief in Serb areas of Bosnia that this never happened, he added.

"Everything is just underfoot, it is not under the ground, I don't think the unities within Bosnia are actually working, the Serb entity of Repubblica Serba, I don't think that is working, and I think the fear is that this will resurrect itself again, There has been no reconciliation in that part of the world and that is a dilemma."

Mr Doyle said the war in Bosnia showed the brutality of close aim conflict. He said it was a brutality that was hard to take in.
