At least 28 people have been killed and 329 injured in a huge explosion in the centre of the Afghan capital Kabul, police and officials say, according to the BBC.

A suicide attacker detonated a vehicle and gunmen stormed the area, reports say. Officials say the gunfight is now over and the area has been cleared.

A Taliban spokesman said the group carried out the attack.

It comes a week after it said it was launching its "spring offensive", warning of "large-scale attacks". 

Afghan security forces cordoned off the area following the explosion.
