BAGHDAD – Back-to-back bomb blasts in a crowded Baghdad market near a revered Shiite shrine and a string of shootings targeting government officials killed at least 17 people Saturday.

The bombings, which happened within about a minute of each other, appeared be aimed at intimidating Iraq’s Shiites, who are a frequent target of Sunni insurgents. Police said at least 11 people were killed and 35 were wounded.

The blasts struck about 500 meters from a shrine where two revered imams are buried, damaging nearby shops and buildings, according to police, who confirmed the casualty figures.

The attacks came as many shoppers were out buying new clothes in anticipation of the Eid al-Adha holiday, which begins Friday.Earlier in the day, gunmen opened fire on a police patrol in the Shiite neighborhood of al-Shaab, killing two policemen and wounding another.

Authorities also said gunmen shot dead a police lieutenant colonel who worked with the State Identity Directorate late Friday in the capital’s Karradah district.

Hospital officials confirmed the deaths in the Baghdad attacks.

Near the northern Iraqi city of Mosul, gunmen attacked a police checkpoint and killed three officers, according to two police officials.Gunmen also shot and killed a prison official in a drive-by-shooting in eastern Baghdad, said Justice Ministry spokesman Haider al-Saadi.
