Officials say separate suicide attacks outside the Iraqi capital have killed at least 10 troops.

Police say the deadliest of Monday's attacks took place in Baghdad's northeastern suburb of Sadr al-Qanat when a suicide bomber rammed his explosives-laden car into a security checkpoint, killing six troops and wounding 13 others.

They added that another suicide car bomber hit a headquarters of paramilitary troops in the town of Mishahda, 20 miles (30 kilometers) north of Baghdad, killing three troops and wounding 10 others.

Medical officials confirmed the causality figures. All officials spoke on condition of anonymity as they were not authorized to release information.

The attacks come as the Islamic State group has lost ground on a number of fronts in Syria and Iraq, where it governs a self-styled Islamic caliphate.
