Nearly one third of Tanzanian girls experience sexual violence before they turn 18, a UNICEF survey has found

The figure among boys is 13.4%, says the UN children's agency. The most common form of abuse is sexual touching, followed by attempted intercourse, it says. The survey also found that of those who had sex before they turned 18, 29.1% of females and 17.5% of males reported that their first encounter was unwilling. This meant they were forced or coerced to engage in sexual intercourse, UNICEF said.
