Art.22 UN Convention on the Rights of the Child: subjecting refugee children to teargas to drive them off is a clear violation of Art. 22 . And Europe stands by.

1. 

States Parties shall take appropriate measures to ensure that a child who is seeking refugee status or who is considered a refugee in accordance with applicable international or domestic law and procedures shall, whether unaccompanied or accompanied by his or her parents or by any other person, receive appropriate protection and humanitarian assistance in the enjoyment of applicable rights set forth in the present Convention and in other international human rights or humanitarian instruments to which the said States are Parties.
