Baghdad, Iraq (CNN) -- Two mortar rounds landed inside Baghdad's heavily fortified Green Zone on Monday, but police did not say whether they caused injuries or damages.
The Green Zone, formally known as the International Zone, houses Iraqi government offices and the U.S. Embassy.
Elsewhere, a car bomb exploded at an Iraqi army patrol in southwestern Baghdad, wounding seven soldiers, police said.
In addition, a roadside bomb went off near a police patrol in another southwestern Baghdad neighborhood, injuring two bystanders, police said.
The attacks came one day after two car bombs exploded in two separate neighborhoods Sunday and killed at least 29 people.
