Security officials in Iraq say two bombings have torn through different neighborhoods in the country's eastern Diyala province, killing at least 42 people.

Officials say the deadlier of the two attacks happened near the provincial capital, Baquba, where a car bomb tore through a marketplace, killing 35 people and wounding at least 72.

The second took place in the province's Kanaan district. Officials say a suicide bomber blew himself up in a residential area, killing seven people and wounding 15.

Hospital officials corroborated the casualties. All spoke anonymously as they are not authorized to speak with the media.

Residents in Diyala have been calling for greater protection from security forces after the Islamic State group bombed a crowded marketplace last month, killing 115 people, including women and children.
