BAGHDAD (Reuters) - A car bomb in central Baghdad killed at least eight Shi'ite pilgrims on Sunday, police and medics said.
Iraq's majority Shi'ites are preparing for the religious festival of Ashura, an event that has been marred by car and suicide bombings in the past.
Earlier, a car bomb targeting Shi'ite pilgrims killed 12 people in Baghdad, police and hospital sources said.
At mosques and shrines across Iraq, millions of Shi'ites are expected to commemorate the slaying of Prophet Mohammad's grandson Hussein at the Battle of Kerbala in 680 AD.
The level of violence this year could be especially high because of the presence of Islamic State militants in Iraq.
The ultra-hardline group believes Shi'ites are infidels who deserve to be killed and is expected to try to capitalize on massive gatherings to try to inflict maximum casualties.
