Several suicide bombers attacked a government complex outside the Iraqi capital, killing at least five soldiers.
Ali al-Issawi, the police chief of the town of Amiriyat Fallujah, in the western province of Anbar, said suicide attackers broke into the government complex on May 14 at dawn.
Issawi said some of the attackers blew up themselves while clashing with security forces, while others holed up inside the buildings and were later killed.
He added that five government soldiers were killed and over a dozen other people were wounded.
The town is located a few kilometers south of Fallujah, the main Islamic State-stronghold in Anbar, about 70 kilometers west of Baghdad.
Iraqi forces have been making steady progress in Anbar this year, retaking full control of the capital, Ramadi, and wresting territory back from IS in several parts of the province.
