A bomb exploded during evening prayers at a mosque in Maiduguri, Nigeria, killing five people and injuring 35. Police suspect a suicide bombing, citing fragments of a vest and witness accounts, and are investigating further. This attack is the latest in the troubled northeastern region, where armed groups like Boko Haram and ISWAP have caused thousands of deaths and millions of displacements since 2009. While no group has claimed responsibility, the method is often attributed to Boko Haram.
