Thirty-four people were killed and several others injured in a suicide bomb attack in front of an education centre in the west of the Afghan capital, Kabul.

The health ministry previously announced the death toll as 48.

 It was revised to 34 today.

It was not clear how many students were at the centre – which specialises in preparing students for university exams – at the time of the attack. 

There was no immediate claim of responsibility for the violence, which was swiftly condemned by President Ashraf Ghani in a statement.
