A young girl was killed and 31 Indian peacekeepers were injured Tuesday in a grenade explosion in Goma in eastern Democratic Republic of Congo, the UN said.

"A grenade exploded regretably killing a girl of roughly eight-years-old... another civilian was injured," said Bilamekaso Tchagbele, the information chief for the UN's force in the country, adding that the blue helmets were struck as they were exercising.
