Shibbir Ahmed, New York — An estimated 20 million children aged 12 to 17—nearly one in five internet-using children—experienced at least one form of technology-facilitated sexual exploitation or abuse in a single year across 21 countries, according to a new report released by UNICEF.

The report, Through Children’s Eyes: How Digital Technologies Enable Child Sexual Abuse, highlights the growing risks children face through social media, online games, messaging services and other digital platforms.

UNICEF said more than 15 million children were exposed to unwanted sexual content, while about 9 million were pressured to engage in sexual conversations or share sexual images against their will. Another 4 million had sexual images of themselves shared without their consent.

Social media accounts for most cases

Nearly 60 percent of reported experiences occurred on mainstream social media platforms, including Facebook, Instagram, Snapchat, TikTok and WhatsApp, according to UNICEF. Another 14 percent of cases occurred through online games, with perpetrators exploiting platform features and children’s trust.

The findings also challenge the perception that online abuse is primarily committed by strangers. UNICEF said 57 percent of cases involved someone the child already knew, including peers, friends, romantic partners or family members. At the same time, 38 percent of children first encountered the perpetrator online, including through fake accounts and private messaging.

Severe impact on children’s well-being

The report found that children who experienced technology-facilitated sexual exploitation or abuse were four times more likely to report suicidal thoughts or behaviours and self-harm, while also reporting significantly higher levels of anxiety.

In Mexico and North Macedonia, the risk of suicidal thoughts or behaviours was more than eight times higher among children who had experienced abuse. In Pakistan, the risk of self-harm was more than seven times higher.

Despite the scale of the problem, most cases remain hidden. More than 40 percent of children never told anyone about their experiences, while fewer than 1 percent of cases were reported to authorities, such as police, social workers or helplines. UNICEF said the most common reason children remained silent was that they did not know where to seek help or whom to tell.

21 countries covered by the research

The UNICEF research covered approximately 21,000 internet-using children aged 12 to 17, along with in-depth interviews with 100 young people who experienced abuse during childhood. The first round of research, conducted primarily in 2020–2021, covered Cambodia, Ethiopia, Indonesia, Kenya, Malaysia, Mozambique, Namibia, the Philippines, Tanzania, Thailand, Uganda and Viet Nam.

The second round, conducted in 2024–2025, expanded the research to Armenia, Brazil, Colombia, the Dominican Republic, Mexico, Montenegro, North Macedonia, Pakistan and Serbia. UNICEF stressed that because the survey included internet-using children, the findings represent internet-using children rather than all children, particularly in countries where internet access remains limited.

UNICEF calls for stronger online protection

UNICEF is urging governments, technology companies and other stakeholders to strengthen protections for children online. The agency called for safer digital platforms, stronger privacy protections, restrictions on unsolicited contact from adults, improved systems for detecting and reporting abuse, and stronger laws and accountability measures.

It also urged governments and communities to provide trusted reporting and support services so children can seek help safely. UNICEF Executive Director Catherine Russell said governments and technology companies must do more to protect children in digital spaces.

The findings come as children increasingly use digital platforms for education, entertainment and social interaction, making online safety an increasingly urgent child-protection issue.

KATHMANDU — At least 22,000 children in Nepal urgently need safe drinking water, sanitation and hygiene assistance more than a week after devastating flash floods swept through the Bhotekoshi-Trishuli river basin, UNICEF said. The floods damaged water-supply systems across affected districts and destroyed or severely damaged toilets and other sanitation facilities, increasing the risk of waterborne and infectious disease outbreaks.

Families displaced by the disaster are also crowded into host households and temporary holding centres, making it increasingly difficult to maintain basic hygiene and access clean water.

“Every parent in these districts is now making the same calculation several times a day,” said Alice Akunga, UNICEF Representative in Nepal, referring to families’ urgent need to determine where they can obtain water and whether it is safe for their children.

UNICEF expands emergency response

UNICEF has already delivered water, sanitation and hygiene supplies for approximately 19,000 people in Rasuwa and Nuwakot, two of the districts hardest hit by the floods. The emergency supplies include more than 3,800 hygiene kits, 3,300 collapsible 10-litre jerrycans, 3,500 buckets, 3,500 one-litre mugs and 4,000 bottles of water-treatment solution. More than 1,000 tarpaulin sheets have also been distributed.

UNICEF teams are working with Nepalese authorities and humanitarian partners on disease surveillance, hygiene awareness and outbreak prevention as the risk of infectious diseases rises.

Schools also heavily affected

The floods have also disrupted children’s education. UNICEF estimates that at least 19 schools have been damaged, including eight that were completely destroyed and another eight that suffered partial destruction. More than 10,000 school-age children are in need of immediate psychosocial support and access to safe learning spaces.

The damage to water infrastructure, homes and schools has left thousands of families facing an uncertain recovery while emergency teams continue providing essential assistance. Humanitarian agencies say restoring access to clean water and sanitation is particularly urgent because prolonged displacement and overcrowded living conditions can accelerate the spread of disease.

The latest warning comes as Nepal continues to recover from one of its most destructive recent flood disasters, with communities across the affected river basin struggling to rebuild homes, infrastructure and essential services. UNICEF said it will continue working with the Nepalese government and partners to provide life-saving water, sanitation, hygiene and child-protection support to affected communities.
