Three people were Saturday killed in separate attacks in northern Iraq, said security officials, the latest incidents in a recent spike in sectarian violence, dpa reported.
A judge died and his son was injured when a bomb placed in their car went off in the town of Tuz Khurmato, some 175 kilometres north of the capital Baghdad.
Elsewhere, a soldier was killed and another wounded when a bomb hit their patrol car in the northern city of Mosul, reported the independent website Alsumaria News, citing police.
A suicide bomber blew himself up at an army checkpoint west of Mosul, added the report. There were no other casualties.
