KINSHASA (Reuters) - Lightning has struck a school in the Democratic Republic of Congo killing 11 children and injuring 85, a U.N. official says. Pupils at a school for 200 students in Bikoro in the northwest of the giant central African country suffered burns or electric shock when the thunderbolt hit on Thursday. "Twenty five of the 85 injured are in a coma," the official told Reuters. "Most of the others have second-degree burns." The school buildings sustained virtually no damage, she said.
