BAGHDAD, Iraq (CNN) -- At least six people were killed and 50 wounded after a suicide car bomber staged a traffic accident as a tactic to draw more victims into the explosion.
The suicide attack happened around midday Sunday at an outdoor market in the city of Tal Afar, an Iraqi Interior Ministry official said.
A man got into a traffic accident and began arguing with the driver of the other car, the official said. According to the official, the man detonated his car bomb as a crowd gathered around the shouting men.
Local police said the incident happened in the same market where a car bombing left more than two dozen people killed and scores wounded in August.
The bombing comes as Muslims observe the holy month of Ramadan, a time when markets are busier than usual with people shopping for food and other items in preparation for the breaking of the daily fast at dusk.
In other developments, four people were killed in two separate roadside bombings on Saturday.
A policeman died when a roadside bomb meant for a Iraqi police patrol detonated north of Baghdad in Diyala's provincial capital of Baquba.
Two men and a woman were also killed south of Baquba when a roadside bomb struck the car they were traveling.
Also on Saturday, the head of security for Iraq's Minister of Justice was wounded in an explosion in Baghdad.
According to a high-ranking security official, Lt. Safiih al-Zaboun was driving to his home for iftar, a fast-breaking meal held at sunset for Ramadan, when an explosive device attached to his car went off.
