A bomb exploded near a girl's school in west Kabul on Saturday, killing at least 30 people, many them young pupils between 11 and 15 years old, Afghan government spokesmen said. The Taliban condemned the attack apparently aimed at civilians, and denied any responsibility.
The explosion is being investigated, said Interior Ministry spokesman Tariq Arian who added the death toll could rise further.
Ambulances were rushing to evacuate wounded from the scene of the blast near Syed Al-Shahdaschool, in the neighborhood of Dasht-e-Barchi, Interior Ministry spokesman Tariq Arian said.
Residents in the area said the explosion was deafening. One, NaserRahimi, told The Associated Press he heard three separate explosions, although there was no official confirmation of multiple blasts. Rahimi also said he believed that the sheer power of the explosion meant the death toll would almost certainly climb.
While no one has claimed responsibility for the bombing, previous brutal attacks in the same neighborhood have been claimed by the Afghan Islamic State affiliate.
In Dasht-e-Barchi, angry crowds attacked the ambulances and even beat health workers as they tried to evacuate the wounded, Health Ministry spokesman GhulamDastigarNazari said. He implored residents to cooperate and allow ambulances free access to the site.
Images circulating on social media purportedly showed bloodied school backpacks and books strewn across the street in front if the school, and smoke rising above the neighborhood.
At one nearby hospital, Associated Press journalists saw at least 20 dead bodies lined up in hallways and rooms, with dozens of wounded people and families of victims pressing through the facility.
Outside the Muhammad Ali Jinnah Hospital, dozens of people lined up to donate blood, while family members checked casualty posted lists on the walls.
Both Arian and Nazari said that at least 50 people were also wounded, and that the casualty toll could rise. The attack occurred just as the fasting day came to an end.
No one immediately claimed responsibility for the attack, and Taliban spokesman ZabihullahMujahid told reporters in a message that only the Islamic State group could be responsible for such a heinous crime. Mujahid also accused Afghanistan's intelligence agency of being complicit with IS, although he offered no evidence.
