A suicide attack rocked the Afghan capital Kabul early Tuesday, the interior ministry said, with civilian casualties feared in what appeared to be the first major assault in the city in months.
No group immediately claimed responsibility for the attack, which comes after nearly three months of relative calm in the capital.
"The explosion was a suicide attack with civilian casualties," the ministry of interior's deputy spokeswoman Marwa Amini said.
A witness near the scene in western Kabul confirmed the blast, saying it happened near the Marshal Fahim military academy.
"It was a big explosion that rocked our house. We also heard gunfire afterwards. Ambulances rushed to the area quickly," resident Samiullah, who goes by one name, told AFP.
The Kabul police chief confirmed the location, according to a local broadcaster.
