France has around 200 military personnel working in Iraq either as trainers or in the headquarters of coalition forces in Baghdad.

"In coordination with the Iraqi government, the coalition has decided to adjust its deployments in Iraq and provisionally suspend training activities," it said in a statement.

The UK defence ministry had already announced some of its troops would come home, citing a "reduced requirement for training" Iraqi security forces.

Iraq's military had halted all training in early March to minimise the risk of the illness spreading among its forces, including from the US-led coalition helping fight remnants of the Islamic State group.
