Officials say attacks inside and around Baghdad have killed at least seven people.

A police officer says drive-by shooters killed a pro-government Sunni tribal sheikh along with his three guards in the town of Tarmiyah, 50 kilometers (30 miles) north of Baghdad. Another officer said three civilians were killed and nine wounded in a bomb explosion at an outdoor marker in Baghdad's western Ghazaliyah neighborhood.

The attacks come as authorities found the bodies for four men and two women dumped in different areas in and around Baghdad, all shot in the chest and head with their hands and legs tied. None had identification cards.

Medical officials confirmed the causality figures. All officials spoke on condition of anonymity as they were not authorized to release information.
