Should "according the United Nations" be "according to the United Nations"?

Or both are correct?

Context:

Argument 2. Our enemies kill children too. The Islamic State of Iraq and Syria (ISIS), Boko Haram and other militant groups have indeed committed atrocities against children, according the United Nations. But we abhor these groups, supposedly, because we find their brutal treatment of civilians (among other acts) inexcusable. Their behavior cannot excuse ours. Moreover, when we commit atrocities, we provide ISIS and other groups with a provocation and justification for their behavior. We should set a moral example for militant groups, not stoop to their behavior.
