A suicide bombing in Afghanistan's capital Kabul has killed at least 95 people and wounded more than 158. The Taliban says it was behind the attack.
Officials say the huge bomb was hidden inside an ambulance. The attacker is believed to have driven through a police checkpoint after claiming he had a patient inside. He then detonated his explosives at a second security post near to the country's old interior ministry.
Despite being closed off to the public, witnesses say the area was packed with people at the time.
Most of those killed were standing next to the ambulance.
One man said:"I was sitting in my shop when a powerful explosion rocked the area. All the windows of my shop shattered but I don't know what happened next."
The number of dead rose rapidly in the blast's immediate aftermath, and is expected to rise further.
While the bombing is the deadliest to hit Kabul in months it comes only a week after Taliban attackers stormed a luxury hotel in the Afghan capital, killing at least 22 people.
