It is one of the biggest blasts to rock the war-torn city in recent years.
The attack triggered chaotic scenes as terrified survivors fled the area scattered with body parts, blood and debris, and hospitals were overwhelmed by the large number of wounded.
It came as both the insurgents and the Islamic State group have escalated their attacks on Kabul, one of the deadliest places in Afghanistan for civilians.
The blast happened in an area where several high-profile organisations, including the European Union, have offices. Members of the EU delegation in Kabul were in their "safe room" and there were no casualties, an official told AFP.

The force of the explosion shook windows of buildings at least two kilometres away and caused some low-rise structures in the immediate vicinity to collapse.
The suicide bomber passed through at least one checkpoint in the ambulance, saying he was taking a patient to Jamuriate hospital.
"At the second checkpoint he was recognised and blew his explosive-laden car," said interior ministry spokesman, Nasrat Rahimi.
Rahimi told a news conference that most of the victims were civilians. He said the Taliban-affiliated Haqqani Network was responsible and four suspects had been arrested.
The Taliban used social media to claim responsibility for the attack, which comes exactly a week after its insurgents stormed Kabul's landmark Intercontinental hotel, killing at least 25 people, the majority foreigners.
