The World Health Organization says the number of children wounded in violence in Somalia increased significantly in May after heavy fighting near Mogadishu's main market.

WHO said Tuesday that 46 percent of weapons-related injuries in May happened to children under 5. That's up from only 3.5 percent in April.

WHO said that burns, chest injuries and internal hemorrhage caused by blasts, shrapnel and bullets were the main causes of death among children under 5.

Somali civilians have borne the brunt of the country's two-decade conflict. Fighting in Mogadishu has increased as African Union and Somali forces move in on the city's insurgent-held market.
