BAGHDAD, Iraq Mar 24 (CNN): Gunmen attacked a bakery in southwest Baghdad on Friday morning, killing four workers, and they left behind a bomb that killed a police officer who rushed to the scene to investigate the shooting, Baghdad police said.
Two hours later, an attack on a police patrol in western Baghdad killed two police officers, police said.
Another seven people were found bound and shot to death, with signs of torture, on the canal road in northeastern Baghdad Friday morning, police said. Hundreds of people have been slain in similar fashion in recent weeks, victims of apparent Shiite-Sunni sectarian strife.
Friday's first attack began at 7 a.m. when attackers opened fire on a bakery in the Saydiyah section of southwest Baghdad. Four bakery workers were killed and one was wounded by the gunfire, police said.
The attackers left a package inside the bakery, and it exploded when an investigator opened it. That officer was killed and another police officer was wounded, police said.
The second attack happened at 9 a.m. in the Mansur section of western Baghdad. Police said gunmen opened fire on a police patrol, killing two officers and wounding a third.
