Afghan officials said at least 15 people have been killed and hundreds others wounded when a car bomb targeted an area in the eastern part of the capital Kabul early on Friday morning.
Police said all the victims are civilians, including women and children, adding that it was a fierce explosion even though the city of Kabul frequently faces such attacks.
The blast killed at least 15 people and wounded 248, said President Ashraf Ghani's office.
"Last night's attack was a cowardly terrorist attack against civilians," presidential spokesman Sayed Zafar Hashemi told reporters.
The bombing, which could even be heard 20 km away from where it took place, damaged buildings and shattered windows around the area, said witnesses.
"I heard a call from watchman here in this house. He called there was a big explosion, me and my father came just at 2 o'clock,” said one witness, who identified himself as Khushal.
“When we came here, there were so many glasses on the street. The whole area was very dark and there was lots of clouds and lots of people were shouting and yelling." he said.
No one has yet claimed responsibility for the attack, but it is the first major attack in Kabul since the new Taliban leader Mullah Omar took over the group’s control.
Taliban’s first attack since the leadership of Omar started took place outside a police compound in Puli Alam, capital of Logar province on Thursday.
More than six people have been killed and 12 injured during the Thursday’s suicide bombing attack that took place in Logar province, south of the Afghan capital Kabul.
