A blast ripped through a market on Friday in Yemen\'s second city Taez, south of the capital Sanaa, killing at least five people, witnesses and a doctor said. More than 10 other people were injured, they said. The explosion occurred when the market re-opened in the evening after the daily fast for the Muslim month of Ramadan, they said. The toll was confirmed by a doctor. A local official told AFP: \"A man carrying explosives on his person detonated the blast,\" but added the motives of the attacker were not yet clear. Taez was a protest hotbed last year during months of unrest against the rule of former president Ali Abdullah Saleh, who stepped down in February.
