KABUL (Reuters) - Eleven people were killed or wounded in a blast in the northern Afghan city of Kunduz, a health official said on Thursday.

       Najeebullah Sahel, from the provincial health authority, said hospitals had received the casualties from a blast and that the numbers could increase, but did not elaborate on the location or cause of the explosion.

       Earlier on Thursday another blast tore through a Shi'ite mosque in the northern city of Mazar-E-Sharif, killing at least five.
