According to the report made by UNHCR on April 10, 2022, it was found that more than half of the Ukrainian refugees are children who are the most vulnerable group because of both physical and mental realities. Most of the children have lost their parents and are unaccompanied minors finding shelter in an unknown country, with people whose culture and language is extremely different hence, they become the victims of violence and sexual abuse. Most of the refugee children worldwide find it difficult to adapt to the new culture of the host country, so they are confronted with psychological problems and ultimately commit suicide in refugee camps. It was reported by the UNHCR that most of the Syrian refugee children are working in the street of Lebanon for four to six hours a day to provide basic needs to their family members, which is a worst violation of human rights. Nearly 2.7 million Syrian child refugees are currently living in Iraq, Jordan, Lebanon, and Turkey. Though a refugee child continuously encounters physical and psychological trauma, Refugee Convention of 1951 and protocol on the status of Refugee 1967 are silent and inadequate to protect refugee children globally. It is the UNHCR and the UNICEF that are helping the child refugees worldwide. Since it was established in 1949 UNHCR has done an admirable job towards refugee children in upholding the best interest of the child. Henceforth, this article will articulate on the distress condition of refugee children in different camps and highlight the working of UNHCR in safeguarding the rights of refugee children globally.
