(CNN) -- A flurry of explosions in the Iraqi cities of Baghdad and Mosul on Monday killed seven people and wounded 16, police said.

A roadside bomb near a restaurant in southern Baghdad killed two and two car bombs near a police checkpoint in the capital's northwestern region killed three. A suicide bomber blew up near an army checkpoint in Mosul, killing two.

This comes as Iraq endures an increase in violence, including an uptick in hostilities between Sunni Arabs and Shiites.
