BAGHDAD — At least 13 people were killed and more than 100 wounded on Friday when two roadside bombs exploded in a Baghdad market, Iraqi police and hospital sources said, in the latest attack this month. Tensions have run high since US troops left in December as Shiite, Sunni and Kurdish political factions vie for power. The first explosion struck Husseiniya, a market in a mainly Shi'ite area on the outskirts of the Iraqi capital, where people were shopping for groceries and other goods, sources said. The second blast followed soon afterwards as security forces and people gathered to tend the casualties from the first. “Fruit and vegetables have been scattered everywhere. Some children were wounded,” said Mudhaffar Khalaf, a policeman at the scene. — Reuters
