Afghan authorities revised down the death toll from a suicide bomb attack on an educational centre in Kabul to 34 from 48, health ministry officials say.

A suicide blast tore through a school in Kabul yesterday killing at least 48 people, while a Taliban attack on a military outpost killed 44 more as a relentless wave of violence continued across Afghanistan.

A motorcycle suicide bomber kills at least eight people near a gathering of Muslim clerics in the Afghan capital after they had issued a fatwa against suicide bombings, officials say, in the latest in a series of attacks to hit Kabul.
