At least 13 people were injured in an explosion that rocked a qat market in Yemen's capital Sana'a, informed sources said on Wednesday.
Three of them were seriously wounded, they said.
An explosive device was detonated at the gate of an inn at the market entrance in Hadda district, but those behind were unknown, they said.
No more details were available, and the authorities did not comment on the incident that comes amid the struggle and major efforts to hunt down AQAP militants and saboteurs.
In recent months, Yemen has taken several measures to maintain security in all governorates as worries about the situation in it started to hamper the influx of foreign investments.
