The explosion took place at the Tabian Farhang centre in Mazar-i-Sharif, the capital of the northern province, as journalists gathered for the award event at 11 am on Saturday, said Mohammad Asif Waziri, the Taliban-appointed spokesman for Balkh police.
At least one person was killed and five others were wounded in this attack.
The incident came two days after a bomb in Mazar-i-Sharif killed the provincial governor, Daud Muzmal, and two others.
