In Bangladesh, 35 per cent students aged 13 to 15 years reported being bullied one or more days in the past 30 days and/or involved in a physical fight at least once in 2014, reports Unicef.
Half of students aged 13 to 15 worldwide - around 150 million - report having experienced peer-to-peer violence in and around school, according to a new report released by Unicef on Thursday.
An Everyday Lesson: #ENDviolence in Schools says that peer violence - measured as the number of children who report of having been bullied in the last month or having been involved in a physical fight in the last year - is a pervasive part of young people's education around the world. It impacts student learning and well-being in rich and poor countries alike.
Meanwhile, nearly 720 million school-aged children live in countries where corporal punishment at school is not fully prohibited.
"Education is the key to building peaceful societies, and yet, for millions of children around the world, school itself is not safe," said Unicef Executive Director Henrietta Fore.
"Every day, students face multiple dangers, including fighting, pressure to join gangs, bullying - both in person and online, violent discipline, sexual harassment and armed violence. In the short-term this impacts their learning, and in the long-term it can lead to depression, anxiety and even suicide. Violence is an unforgettable lesson that no child needs to learn."
The report outlines a variety of ways students face violence in and around the classroom.
According to the latest available data from Unicef, globally, slightly more than 1 in 3 students aged 13-15 experience bullying, and roughly the same proportion are involved in physical fights.
And 3 in 10 students in 39 industrialised countries admit to bullying peers.
In 2017, there were 396 documented or verified attacks on schools in the Democratic Republic of the Congo, 26 on schools in South Sudan, 67 attacks in the Syrian Arab Republic and 20 attacks in Yemen.
While girls and boys are equally at risk of bullying, girls are more likely to become victims of psychological forms of bullying and boys are more at risk of physical violence and threats.
The report noted that violence involving weapons in schools, such as knives and guns, continues to claim lives. It also says that in an increasingly digital world, bullies are disseminating violent, hurtful and humiliating content with the tap of a key.
An Everyday Lesson: #ENDviolence in Schools is released as part of the Unicef #ENDviolence global campaign.
It is also part of a collective effort to shed light on and spark action to #ENDviolence in and around schools by organizations including Unicef, the United Kingdom's Department for International Development (DFID), UNESCO, other members of the Global Partnership to End Violence Against Children and UNGEI.
To end violence in schools, Unicef and partners called for urgent action including implementing policies and legislation to protect students from violence in schools.
It called for strengthening prevention and response measures in schools and urged communities and individuals to join students as they speak up about violence and work to change the culture of classrooms and communities.
The Unicef called for making more effective and targeted investments in proven solutions that help students and schools stay safe.
It called for collecting better, disaggregated data on violence against children in and around schools and sharing what works.
Unicef encouraged young people around the world to raise their voices to #ENDviolence in and around schools and to tell us how they are working together and what solutions they are using to #ENDviolence in and around schools once and for all. Find out more at https://uni.cf/end-violence.
