title: Suspected Boko Haram suicide bombers kill at least 13 in Nigeria: officials
text: BAUCHI, Nigeria (Reuters) - Suspected Boko Haram suicide bombers have killed at least 13 other people in an attack on a market in the northeast Nigerian town of Biu in Borno state, officials said on Saturday. The blasts struck while aid workers were distributing food to people affected by the eight-year conflict with Boko Haram, said Aliyu Idrisa, a community leader. In addition to the 13 victims, 53 people were injured and two bombers were killed, said Victor Isuku, police spokesman for Borno state. Saturday s attack bore the hallmarks of Boko Haram, which uses suicide bombers, often women and girls, to attack crowded public spaces.  Last week, a suicide bombing at a mosque in the northeastern town of Mubi killed at least 50 people, one of the deadliest attacks in recent years. The government has said its long-term plan for the northeast is to corral civilians inside fortified garrison towns and effectively cede the countryside to Boko Haram. That plan and a string of deadly attacks have raised questions about assertions by the Nigerian government and military that Boko Haram s Islamist insurgency has been all but wiped out.
