"They are creating a problem for this country by their incompetence and by trying to utilise Kashmir as a political asset," Gandhi told reporters here.
The government of India and the Prime Minister "are completely mishandling Kashmir. Kashmir is India's strength and they are making it India's weakness," he said, blaming the Modi government for the current unrest in the Valley.
The Congress Vice President said he had told Union Minister Arun Jaitley about six-seven months back that they were "mishandling Kashmir and they are going to set it afire".
He said the opposition would unitedly "fight and defeat" the attempts of the BJP and the RSS to "thrust one idea" on a country that celebrates diversity.
"We are not going to allow one single idea of the RSS - the bankrupt idea, to invade this country and we are going to fight the RSS together," he said.
Opposition parties stood united in this task to defeat the BJP and the RSS, he added.
