Back-to-back suicide bombings killed at least 25 people Friday outside the most important Shi'ite shrine in Baghdad, police officials said.
The blasts in the northern neighborhood of Kazimiyah come a day after nearly 80 people were killed in attacks, making it the deadliest day in Iraq in more than a year.
The suicide bombers Friday detonated explosive belts within minutes of each other near the gates of the tomb of Imam Mousa al-Kazim, an important Shi'ite saint, said a police official. Another police official said the bombers struck shortly before the start of Friday prayers as worshippers streamed in to the mosque - an important site for Shi'ite pilgrims.
About 60 people also were injured in the blast, said the same official.
Both officials spoke on condition of anonymity because they were not authorized to release the information.
