A roadside bomb exploded early Friday outside a motorcycle shop in central Baghdad, killing a civilian, police said. Four others were wounded by the blast and transferred to a nearby hospital, they said. Some damaged was sustained to buildings next to the shop. About an hour earlier, gunmen opened fire on the same spot, wounding one civilian, police said. The attacks took place near the Abdul-Qadir al-Gailani mosque, a Sunni shrine in central Baghdad's Sinak district, a mixed area.
