According to the independent newspaper, a suicide bomber has attacked an Afghan military convoy outside Kabul killing around 30 police officers, officials say.
A police official said at least 27 people had been killed and more than 40 had been injured after three buses full of police cadets were attacked as they approached the city from neighboring Wardak province.
The unnamed official said: “Initial information we have is that two suicide bombers were involved and there are many casualties.”
The Taliban’s official spokesman, Abdulqahar Balkhi, claimed responsibility for the attack on Twitter.
It comes just over a week after a similar attack on a bus carrying Nepalese security guards working for the Canadian embassy which killed 14 people in the capital.
The newspaper added that the country suffered its deadliest assault since 2011 in April after at least 64 people were killed in a Taliban attack on a security services facility.
