"Brigade 16 of the Hashed al-Shaabi found a tunnel on the outskirts of Rashad and killed 10 ISIS suicide bombers," the pro-government paramilitary group said in a statement.

Rashad was captured by Iraqi forces on October 2.

The clash followed Iraqi Prime Minister Haider al-Abadi’s declaration of victory against ISIS. Al-Abadi said that ISIS had been routed from their last pockets on the border with Syria.
