Gorkhaland:Hunger strike by High school children: Isn't it a violation of UN convention on child rights

I was talking with a teacher friend of mine from Darjeeling to know about the declared hunger strike by students. He confirmed that children under the age of 18 yrs are also sitting in hunger strike. This strike is going on in all the major towns of darjeeling Hills at Darjeeling, Kurseong, Kalimpong and Mirik.
This is a violation of UN convention on Child rights . The political leaders can in no form use the children to fulfill their aspirations. This is deliberate and intentional. I urge the United Nations and Government of India to interfere in this matter and stop Bimal Gurung and Gorkha Janmukti Morcha in continuing this act.
Why civil society is silent in this matter? Why parents are mumb? Why women groups are encouraging this?
