Kabul shrine hit by deadly explosion on Shia holy day

Twin attacks apparently targeting Shia Muslims have killed at least 58 people in Afghanistan.

In the deadliest incident, a suspected suicide bomb struck a shrine packed with worshippers in the capital, Kabul, killing at least 54 people.

Another blast struck near a Shia mosque the northern city of Mazar-i-Sharif at about the same time, killing four.

The attacks appear to be of a sectarian nature unprecedented in recent Afghan history, as the BBC's Quentin Sommerville in Kabul explains.
