In Nigeria, the UN has warned that at least 49,000 children in Borno state will die of malnutrition this year, if they do not receive timely help.<br/><br/>The UNICEF in a report said that nearly half a million children around Lake Chad face severe acute malnutrition due to drought and a seven-year violent campaign by the armed group, Boko Haram. It said, despite the military gains, 2.2 million people remain trapped in areas under the control of Boko Haram or are staying in camps, fearful of going home.<br/><br/>The war between Boko Haram and the Nigerian government has left at least 20,000 people dead in six years and made more than 2.6 million homeless.
