The attacks came just hours after the Iraqi government yesterday announced the start of a wide-scale operation to recapture areas under the control of the IS group in Anbar.
Brig. Gen Saad Maan Ibrahim, the spokesman for the Joint Military Command, told The Associated Press the attacks took place outside the Islamic State-held city of Fallujah late last night.
Ibrahim added that the Islamic State extremists used a sandstorm that engulfed most of Iraq last night to launch the deadly wave of bombings. He said it was not clear how many suicide attackers were involved in the bombings but they hit the military from multiple directions.
Last month, the water station near Fallujah fell into the hands of Islamic State militants following attacks that also included multiple suicide bombings and that killed a general commanding the 1st Division and a dozen other officers and soldiers, he said.
The Iraqi operation to retake Anbar, which is said to be backed by Shiite militias and Sunni pro-government fighters, is deemed critical in regaining momentum in the fight against the Islamic State.
The extremists captured Ramadi in Iraq and the Syrian ancient town of Palmyra earlier this month, showing that it is able to advance in both countries despite months of US-led airstrikes. Capt. Andrew Caulk, a US Air Force spokesman in Qatar, told the AP it will continue to provide air support "to government-controlled Iraqi forces" throughout the country, including near Ramadi, where it has been carrying out airstrikes for several months.
