A suicide bomb attack on Shia Muslim worshippers in the Afghan capital Kabul has killed at least 58 people and wounded more than 160 others. The blast happened on the most holy day of the Shia calendar. From Kabul, Quentin Sommerville reports.

At a Kabul hospital, wave after wave of victims arrive. And on the pavement outside, a mother mourns for her lost son. "My heart is broken," she cries. Desperate and in despair, more gathered for news of missing family and friends. For many, a day of Muslim mourning became a day of terrible loss. The Taliban issued a statement saying they didn't carry out this attack. The Afghan government says they are lying. But whoever is responsible, it's brought a new kind of suffering to this already fractured country.
