Colombia admits responsibility in 'extermining' political party Colombian President Juan Manuel Santos recognized Thursday that the Colombian state didn't take the "necessary measures" to avoid the "extermination" of the political party Union Patriotica in the 1990s and pledged to make sure no other party is ever a victim of political violence. The UP party emerged from a failed round of negotiations with the FARC in the 1980s and later faced an extermination campaign from far right paramilitary groups. IMAGES AND SOUNDBITES
