Bombs found at an abandoned stronghold of Boko Haram militants exploded, killing at least 13 people and injuring 45 others in northeast Nigeria, locals and a hospital source said. At least two of the devices went off as people were taking them past a market to be defused at a military base on Tuesday afternoon, locals told Reuters. The explosives were found in a bag on the side of a road outside the town of Monguno in Borno state. "The bombs killed 10 of our members and three other persons nearby," Umar Zannah, a member of a local militia force set up to defend the town, said. "We have commenced treatment of the 45 people who were injured from the blast," added a doctor at Borno Specialist Hospital who did not want to be named.
