Iraqi authorities say a car bomb and a shooting have killed six people in the country's north.

The explosion killed four people and wounded 28 others on Friday on a commercial street in Tuz Khormato, said the town's mayor Shalal Abdoul.

Tuz Khormato is 210 kilometers (130 miles) north of Baghdad.

In the northern city of Mosul, gunmen shot dead two members of the Shabak minority in a drive-by shooting, said police and hospital officials.

The Shabak are small ethnic minority, many of whose members follow an offshoot of Islam. Most live in villages east of Mosul, the provincial capital of the ethnically mixed Ninevah province that is predominantly Sunni Muslim.

Both officials spoke on condition of anonymity because they are not authorized to speak to media.
