Scores of people have died in a string of attacks across Iraq.
In Baghdad Saturday, a suicide bomber killed nearly 50 Shi'ite pilgrims who were on their way to a prominent Shi'ite shrine.
Earlier in the day, 12 people were killed when a suicide bomber detonated explosives inside a cafe in Balad, 80 kilometers north of the capital. An almost identical bombing killed at least 16 people at the same cafe seven weeks ago.
Separately, security sources say unidentified gunmen killed two Iraqi journalists as they were filming in the northern city of Mosul. The journalists worked for the Iraqi television channel al-Sharqiya news.
Militants have stepped up attacks on cafes and other public gathering places, including mosques, funerals and busy market places, in recent months.
Deadly violence has climbed to its highest level since 2008, with analysts repeatedly voicing fears the country is sliding back into Sunni-Shi'ite civil war.
