BAGHDAD, Iraq (CNN) -- Suicide bombers in Iraq launched two deadly attacks Thursday, killing at least 45 people in Diyala province and at least 28 in Baghdad, an Iraqi Interior Ministry official said. An attacker set off a suicide vest at a restaurant in Imam Wais, a Diyala provincial security official said. The area is about 43 miles (70 kilometers) northeast of Baquba, capital of the sprawling province that is north and east of Baghdad.
The Diyala bombing, which targeted Iranian pilgrims, also wounded 28, the Interior Ministry official said.
The
Diyala security official said the pilgrims -- who had been visiting Shiite shrines -- stopped for lunch at the restaurant when the attack occurred.
Many pilgrims were among the casualties, and the restaurant collapsed after the
bombing, the security official said.
In central Baghdad, a bomber clad in a suicide vest attacked a crowd of national police, killing 28 police and civilians and wounding 52. Police had been helping the Red Crescent distribute aid to displaced families in the Karrada district.
Despite the declining levels of violence in Iraq over recent months, the latest strikes reflect what appears to be a slight uptick from March to April of assaults on civilians, U.S. and Iraqi security forces, and the U.S.-backed militias called Awakening Councils or Sons of Iraq.
