An Afghan official says at least three people have been killed in a bombing at a tea house in northern Afghanistan.

The deputy governor of Faryab province Abdul Sattar Barez says Tuesday's blast occurred around 11 a.m. in a restaurant in the upscale district of Khwaja Sabz Poshi Wali.

Barez gave the death toll and says 10 other people were wounded.

Nobody claimed responsibility for the blast, but the Taliban and allied militant groups have been active in the area, which has seen several big blasts in recent months.
