An estimated 345 children die violent deaths around the world every day, and 75 per cent - or 258 - of those incidents happened in countries that are not at war.   Children 'experience extreme violence in everyday life, everywhere', said Susan Bissell, global head of child protection for UNICEF.In some countries, deaths from violence are diminishing gains made in preventing childhood deaths from disease or hunger.Ms Bissell said: 'What is shocking is that we have for two or three decades focused a lot, and importantly, on child mortality from preventable diseases, and what this report says is that we need to be thinking about child mortality from all causes.'And it's shocking to imagine that we might not achieve our goals in terms of child survival if we don't address the protection of children. These go hand in hand.'In Brazil, the number of children dying from preventable disease before the age of five has dropped since 2000, but almost 15,000 lives have been lost to violence in adolescence. Millions of children are vulnerable to physical, sexual and emotional abuse in their homes, schools and communities, said Leah Kreitzman, head of campaigns and advocacy for UNICEFUK.(dailymail.co.uk)Bakudaily.Az
