BAGHDAD

Four people were killed in two separate attacks in eastern Iraq on Saturday, according to a local police officer. 

Daesh/ISIS militants attacked a police checkpoint in Buhriz, south of Diyala province, killing two policemen, captain Habib al-Shimari told Anadolu Agency.

He said a husband and his wife were also found dead inside their home in the same area.

Iraqi authorities have launched an investigation to determine the group behind the killing.

In mid-2014, Daesh/ISIS overran roughly one-third of Iraq.

By late 2017, the Iraqi army -- with the help of the U.S.-led military coalition -- recovered most if not all the territories lost to the terrorist group.

Although officials in Baghdad say Daesh/ISIS presence in the country has been largely eradicated, the terrorist group has continued to stage sporadic attacks in Iraq's Diyala, Nineveh, Kirkuk, Saladin and Anbar provinces.
