The UN has sharply criticised President Donald Trump's decision to pardon four former Blackwater contractors jailed over the killing of 14 Iraqi civilians.
Nicholas Slatten, Paul Slough, Evan Liberty and Dustin Heard opened fire in Baghdad's Nisoor Square in 2007 while guarding an American diplomatic convoy.
The UN Human Rights Office warned that the pardons would serve to embolden others to commit similar crimes.
The father of a nine-year boy who died said Mr Trump "broke my life again".
There was no immediate response from the Iraqi government.
