Kabul, Jan 10: Twin explosions were heard near the Afghan Parliament in Kabul on Tuesday and the interior ministry said there could be scores of casualties in the latest terror attack.
23 people have been killed and more than 20 have been injured, according to Reuters.
At least one of the blasts was apparently caused by a car bomb, ministry spokesman Sediq Sediqqi said.
"They targeted employees of Parliament, there have been casualties," a second security source said.
The Afghan Taliban has claimed responsibility for the twin blasts, which they said had killed or wounded scores of people, Reuters reported.
The attack targeted a minibus carrying staff from the NDS, Afghanistan's main intelligence agency, and as many as 70 people were killed or wounded, the insurgents said. There was no immediate confirmation of casualty numbers from the police.
The attack, which ended a period of relative calm in the Afghan capital, occurred in a crowded area during the afternoon rush hour as workers were returning home.
Officials said a suicide bomber blew himself up in the Darul Aman area of the city near the new Indian-financed Parliament building and was followed immediately by a car bomber in an apparently coordinated operation.
Earlier on Tuesday, a suicide bomber killed seven people and wounded nine when he detonated explosives in a house in the southern province of Helmand used by an NDS unit.
