During Indhira Gandhi's tenure as Prime Minister of India,Indhira Gandhi Brought various tamil groups from srilanka and gave them military training:Her aim was to divide(as she did Bangladesh) Srilanka into two:post her death,her son,Rahul Gandhi took a nose dive and started to support srilankan Govt.to fight against the tamil community!
The undue side effect was routine inflow of refugees from srilanka to India!
