At least 12 people died and dozens were wounded in attacks against Shi'ites and police around Iraq, Iraqi Interior Ministry officials told Efe on Tuesday.

The bloodiest attack killed four Shi'ite pilgrims and wounded 13 others in the city of Al Mahmudiya, some 20 kilometers (12 miles) south of Baghdad.

A suicide bomber detonated his explosives-laden belt near the pilgrims, who were en route to the holy Shi'ite city of Karbala.

Three other Shi'ites lost their lives and seven were wounded in a grenade attack in southeastern Baghdad, also as they were on the way to Karbala, where the Imam Hussein Shrine, a sacred site for Shi'ites, is located.

In the Al Mashtal area of the capital, a similar attack killed two Shi'ites and wounded 15.

Currently, Shi'ites are commemorating the 40 days following the anniversary of the death of Hussein, the much-venerated nephew of the Prophet Mohammed.

Meanwhile, an armed group attacked a police checkpoint, killed two officers and wounded three others in the Al Riash zone near the city of Biyi.

Also in Biyi, which is located in Salaheddin province, a police official died when a bomb that had been attached to his automobile blew up.

Iraq is experiencing a resurgence of sectarian violence and terrorist attacks, which killed 948 people during the month of November, most of them Shi'ites, according to government figures. EFE
