A blast rocked Darul Aman road in Police District 3 of Afghanistan's capital Kabul on Tuesday.
Casualties are feared, Xinhua reported citing eyewitnesses.
No terror group has claimed the responsibility for the attack.
Since the Taliban takeover of Afghanistan in mid-August, attacks by ISIL-affiliated terrorists against them have increased.
The rise in terrorist attacks has raised the possibility of a wider conflict between the two groups.
Further details are awaited.
