BAGHDAD (AP) — Two bombs exploded in an open-air market in Baghdad on Friday, killing at least 14 people in the latest round of spiraling violence six months after the last U.S. troops withdrew from Iraq.

More than 160 people have died this month in attacks mostly attributed to Sunni insurgents linked to al-Qaida. They are targeting security forces and Shiite civilians in an attempt to weaken Iraq’s fragile government, which is mired in deadlock and struggling to provide security and even basic services like electricity.
