A mine awareness team in Uganda was horrified to find an unexploded bomb being used as a bell when they visited a school to teach children how to spot bombs

The Anti-Mine Network organization saw teachers banging the bomb with stones to call children to lessons in a 700-pupil school in a rural area. "Its head was still active, which means that if it is hit by a stronger force, it would explode instantly and cause untold destruction in the area," Wilson Bwambale, coordinator of the organization, said. The Ugandan military has fought two rebel insurgencies over the last two decades and mines and bombs still litter former battlefields around the country. This is the second bomb that the Anti-Mine Network have found in a Ugandan school in 2011. Another was found being used by children at lunchtime as a toy and put away in a storeroom during lessons.
