MOGADISHU, Shawwal 07, 1435, August 03, 2014, SPA -- Three women were killed in the Somali capital on Sunday, and seven others were wounded when a remotely detonated bomb exploded in a busy market, police and witnesses said. It was not immediately clear who was behind the bombing. In recent weeks, Al Shabaab insurgents have increased gun and bomb attacks in Mogadishu, with the latest incident on July 5, when its fighters attacked the presidential palace. The women killed in the blast were city workers, who were cleaning the streets when a bomb hidden in a rubbish pit exploded in the busy market sector known as Hodan district of Mogadishu, police said. "We heard a big blast, and then I could see the old mothers who were cleaning the scene lying, some of them dead and others screaming. The bomb was wrapped in a big, black plastic bag and then placed inside the rubbish along the Taleh street," Nuria Ahmed, a mother of four who lives near the scene, told Reuters. --SPA 11:42 LOCAL TIME 08:42 GMT www.spa.gov.sa/w
