In her Independence Day message, Mrs Gandhi greeted fellow Indians and wished them progress and prosperity on the 71st Independence Day.
"The need today is that all Indians in one voice should fight separatism, terrorism and all such forces who divide and spread hatred in society, and unite to protect the basic principles of Indianness," she said in her message.
She said, "I pray that this nation must always progress and move forward and we all feel proud being an independent Indian... My best wishes to you all that this 71th year will bring prosperity and happiness to all of you and will be in good health and will get immense opportunities for growth and progress."
