A Baghdad court sentenced two more Frenchmen to death Tuesday (May 28th) for joining the "Islamic State of Iraq and Syria" (ISIS), raising the number of French ISIS members on death row in Iraq to six, AFP reported.

Brahim Nejara and Karam El Harchaoui were among 12 French citizens transferred to Iraqi authorities in January by the Syrian Democratic Forces (SDF).

The court's ruling came despite France reiterating its opposition to capital punishment after a series of similar rulings this week against French citizens handed over to Baghdad.

In recent months, Iraq has taken custody of thousands of extremists, including foreigners, captured in neighbouring Syria by the SDF.

Four other French citizens -- Kevin Gonot, Leonard Lopez, Salim Machou and Mustapha Merzoughi -- have been given death sentences in recent days by a Baghdad court.

Nejara, 33, was involved in ISIS's foreign fighter operations, according to the French Terrorism Analysis Centre.

He allegedly helped foreign fighters join ISIS in Syria, persuaded one of his brothers to commit an attack in France, and was associated with one of the suicide bombers at the Bataclan theatre during the 2015 Paris attacks.

Harchaoui, 32, left for Syria in 2014 from Belgium.

They have 30 days to appeal.

The remaining six face trial in the coming days.
