A former security guard for the US firm Blackwater has been found guilty of murder for his role in a notorious massacre of unarmed civilians in downtown Baghdad in 2007.

Nicholas Slatten, 35, was convicted of first-degree murder by a federal jury in Washington on Wednesday after five days of deliberations.

Slatten was convicted of killing Ahmed Haithem Ahmed Al Rubia’y, 19, an aspiring doctor who was one of more than a dozen civilians killed by Blackwater guards in Baghdad’s Nisour square on 16 September 2007.

While escorting a diplomatic convoy, Blackwater guards opened fire in the bustling square with sniper rifles, machine guns and grenade launchers – allegedly without provocation – leaving at least 14 civilians dead and at least 18 wounded. The Iraqi government says the toll was higher.

The shooting deepened the resentment of Americans in Iraq four years after US forces toppled dictator Saddam Hussein and raised questions about the expanded use of armed contract guards by the US government.

The US attorney’s office presented testimony from 34 witnesses during the trial, including four who came to the United States from Iraq to testify.

According to the government’s evidence, Slatten, of Sparta, Tennessee, was the first to open fire.

No date was set for his sentencing. The US attorney’s office said the murder charge calls for a mandatory sentence of life in prison.

It was Slatten’s third trial on the charges. His first conviction was thrown out and the jury was unable to reach a unanimous verdict at his second trial.

Slatten was one of four Blackwater guards who were found guilty in 2014. He was originally sentenced to life in prison while the three others were given 30-year prison sentences

An appeals court has ordered that the three other Blackwater guards be resentenced. They are currently in custody pending resentencing.
