Residents in a city west of Baghdad say the Islamic State group has paraded Iraqi troops captured in battle earlier this week in a show of strength in the militant stronghold.

Fallujah residents say about 30 men in Iraqi military uniform were driven in the back of seized military vehicles through the city on Tuesday. Fallujah is about 30 miles west of Baghdad.

Residents say militants driving the convoy blasted songs glorifying the leader of the Islamic State group, Abu Bakr al-Baghdadi, as they paraded their captives. The residents spoke on condition of anonymity, fearing for their safety.

On Sunday, Islamic State fighters disguised in Iraqi army uniforms and driving stolen Humvees attacked an Iraqi army camp in the western Anbar province, killing 40 troops and capturing 68.
