Gunmen attacked an Iraqi police checkpoint Sunday morning, leaving five people dead, authorities said.
Two police officers and a member of the pro-government Sons of Iraq militia were killed, as were two of the attackers, police said.
The checkpoint was in the town of al-Asoud, north of Baquba, which is about 37 miles (60 kilometers) north of the capital Baghdad.
It was one of two fatal attacks carried out in the country Sunday.
At least one person was killed in the other incident -- a car bombing in the al-Dawasa commercial neighborhood of central Mosul on Sunday afternoon.
Three people were wounded in the bombing, including two police officers, authorities said.
Mosul is about 260 miles (420 km) north of Baghdad.
