Baghdad (CNN) -- A suicide attack on an Iraqi police station in the southern city of Basra killed at least four people and wounded 19 others Monday morning, a police official said.
The bomber detonated a car loaded with explosives at an emergency police station in the al-Ashar neighborhood in central Basra, said Police Chief Faisal Al-Abadi.
Basra is located about 480 kilometers (nearly 300 miles) south of Baghdad.
A recent wave of violence has raised questions about the capability of Iraqi security forces to protect the country as U.S. troops prepare to leave by January 1.
