At least seven people have been killed in a roadside blast in northern Afghanistan.
According to officials, those killed in the blast include employees of a petroleum company on a bus.
An official of the Balkh police department in Mazar-i-Sharif, Asif Waziri, said the bomb was placed in a cart by the roadside, and was detonated as the bus arrived.
It was not immediately clear who was behind the attack, which comes amid repeated pledges from the Taliban government to bring security to Afghanistan following decades of war.
