A first bomb struck a civilian car and the second hit a police patrol in the Abu Saida district, the Security Media Cell stated.
Security forces are inspecting the area and have blamed the Islamic State group (ISIS) for the attack. There has been no immediate claim of responsibility.
Although the Iraqi government announced the territorial defeat of ISIS in December 2017, remnants of the group have returned to earlier insurgency tactics, ambushing security forces, kidnapping and executing suspected informants, extorting money from vulnerable rural populations, and carrying out bomb attacks.
ISIS remnants in Iraq are most active in territory disputed between Erbil and Baghdad, notably in the northern provinces of Salahaddin, Diyala, and Kirkuk. The Kurdistan Region is generally considered to be more secure, but still occasionally faces terrorist threats.
In the latest edition of its propaganda newspaper al-Naba, ISIS claimed it had conducted 11 attacks across Iraq, including 4 in Diyala from April 7 to 14, killing and injuring 29 people.
