About one in 10 girls around the world experiences serious sexual violence, the UN children's agency has said in a major report detailing the "staggering extent" of sexual, physical and emotional abuse faced byyoung people.

The Unicef report found that 120 million girls and female adolescents under 20 had endured rape or other forced sexual acts, with such experiences especially common in some developing countries – about 70% of girls suffer sexual violence in the Democratic Republic of the Congo and Equatorial Guinea, and an estimated 50% in Uganda, Tanzania and Zimbabwe, Unicef said.

The report also pointed to problems in richer countries, with many girls reporting "sexual victimisation", for example, by harassment or exposure to pornography.

Many young victims did not report abuse, the authors found, with data showing that nearly half of all girls aged 15-19 who said they had faced physical and/or sexual violence had never told anyone about it.

The report also highlighted the high numbers of young people murdered every year, totalling about 95,000 deaths in 2012. In some countries, for example Panama, Venezuela, Brazil and Colombia, murder is the leading cause of death for males aged 10-20. Nigeria alone had 13,000 child and adolescent homicides in 2012, with some 11,000 in Brazil.
