Mogadishu - A roadside bomb struck a minibus north of the Somali capital Mogadishu late on Saturday, killing two people and injuring six others, police said. The blast occurred on a busy road in the Elasha district less than 20 kilometers northeast of the capital, said Dahir Ahmed, a police major. "The bomb killed the driver and a woman and injured six other civilians," he told Reuters. There was no immediate claim of responsibility, although the Islamist Al-Shabaab group has carried out regular attacks on officials, government offices and civilian sites. Al-Shabaab is waging an insurgency to overthrow the U.N.-backed government and drive out the African Union peacekeeping force that supports it.
