Ninety people have been killed and 400 injured in a powerful car bomb blast that ripped through a diplomatic district in Afghanistan’s capital, Kabul, the government’s media center has reported, according to AP.

The Afghan Interior Ministry previously said that 64 people had been killed, according to AFP.

The blast is believed to have come from a car bomb. Reuters reported that the powerful bomb was hidden inside a sewage tank on a truck. The precise target was not immediately clear, but many embassies and government buildings are located in the area.

Afghanistan’s President Ashraf Ghani condemned the devastating attack, which happened just days into the Muslim holy month of Ramadan. In a statement quoted by Reuters, Ghani said “the terrorists, even in the holy month of Ramadan, the month of goodness, blessing and prayer, are not stopping the killing of our innocent people.”

The blast struck at around 8:30am local time Wednesday.

Several hours after the attack, AFP reported that ambulances were still taking the wounded to hospital and rescuers were retrieving bodies from the rubble while firefighters struggle to extinguish flames in adjacent buildings.
