According to the text snippets, there are several examples of violations of the right to education in different countries such as Bangladesh, Madagascar, and Yemen. These violations are carried out by non-state actors such as individuals and companies, and there are approximately 260 million children worldwide who do not have access to education. Despite the right to education being a fundamental human right, many children and adolescents living in disadvantaged families are unable to exercise this right. UNICEF and other organizations have made efforts to improve access to education, and there have been some positive results in countries like Afghanistan. However, there are still many rights, including the right to education, that are being violated, and it is crucial to address these issues to ensure full and equal opportunities for all individuals.
