Northern Ireland

More than 3,600 people were killed in the conflict known as The Troubles.

Republican and Loyalist paramilitary groups carried out most of the killings; the UK security forces are estimated to be directly responsible for about 10 percent of the deaths, but there is also evidence of numerous instances of collusion between these forces and paramilitaries.

One of these cases was Gerard Slane, who was murdered by a loyalist paramilitary group, the UDA, in a killing linked to the security forces.

His wife Teresa is still fighting for truth and justice.
