The attacks come after Iraqi forces aided by U.S.-led airstrikes drove IS militants out of the city center of Ramadi, the capital of the sprawling Anbar province west of Baghdad. Following that victory a week ago, U.S. Officials said the extremist group has lost 40 percent of its territory in Iraq and 20 percent in Syria.
Khalid Salman, a provincial councilman from Haditha, and Shaalan al-Nimrawi, a local tribal sheikh, confirmed the casualty figures among the Iraqi forces.
Iraqi forces held onto Haditha and a nearby hydroelectric dam as IS overran much of Anbar province in the summer of 2014. The U.S.-led coalition launched airstrikes near the dam to protect it in September of that year.

IS militants "don't have the ability to hold terrain," said U.S. Army Maj. Michael Filanowski, adding that the extremist group had suffered heavy casualties as it lost territory.
"Those attacks were limited in nature -- what we call harassing attacks," said Col. Steve Warren, the Baghdad-based coalition spokesman, adding that Iraqi government forces were able to "either push the attackers back immediately or regroup and counterattack with the support of coalition airstrikes."
Despite the recent losses, IS still holds much of northern and western Iraq, including Mosul, the country's second largest city. It also controls Fallujah, a town near Ramadi where U.S. Troops fought some of their bloodiest battles in the years after the 2003 invasion that toppled Saddam Hussein.
"The coming days will witness big and pitched battles to liberate what remains of our territories," he said.
