At least 7 killed, 6 injured in blast in northern Afghanistan

A roadside bomb killed seven petroleum company employees aboard a bus in northern Afghanistan on Tuesday, a provincial police spokesman said.

"The bomb was placed in a cart by the roadside. It was detonated as the bus arrived," said Asif Waziri, of the Balkh police department in Mazar-i-Sharif, according to an AFP report.

Although the Taliban claim to have improved security across the nation since storming back to power in August last year, there have been scores of bomb blasts and attacks — many claimed by the Daesh.

At least 19 people were killed and 24 others wounded earlier this month by a blast at a madrassa in Aybak, southeast of Mazar-i-Sharif.

Waziri told AFP that Tuesday's blast happened around 7am (02.30 GMT) near Sayed Abad Square in the city.
