A new study says the ongoing conflict in the Democratic Republic of Congo is killing around 45,000 people each month — half of them small children under the age of five. The International Rescue Committee says the war in the Congo is the deadliest conflict since the Second World War, with 5.4 million people killed over the past decade. The majority of deaths were attributed to preventable conditions worsened by the fighting, including infectious diseases, malnutrition and pregnancy-linked fatalities.
