BAGHDAD — Bombings and shootings across Iraq on Saturday killed at least 19 people, including an ambush that targeted a convoy carrying a top military commander in the country, authorities said.

Violence has been on the rise in Iraq all year, but the number of attacks against civilians and security forces has spiked during the Islamic holy month of Ramadan, which began early last month. The surge in the bloodshed is raising fears of a return to the widespread killing that pushed the country to the brink of civil war after the 2003 U.S.-led invasion.

The deadliest attack involved an ambush targeting the motorcade of Lt. Gen. Abdul-Amir al-Zaidi, a top military commander, in an area north of Baghdad. Gunmen killed six of al-Zaidi’s bodyguards and wounded four others, police said. The attack took place near the town of Adeim, about 100 kilometers north of Baghdad.

Al-Zaidi, who commands some government forces in Diyala and Salahuddin provinces, was not hurt in the attack, police said.
