Addressing an election rally here, Modi congratulated the scientists for developing the defence system.
He said the opposition would now come seeking the proof of the successful test.
"They (opposition) ask proof of surgical strikes. Now if they question this feat, they have to travel very high to check its authenticity," he said at an election rally here.
His remarks came hours after India successfully test-fired its interceptor missile off the Odisha coast, achieving a significant milestone in the direction of developing a two-layered Ballistic Missile Defence system.
Days after the government said its troops carried out surgical strikes by crossing the Line of Control to hunt terrorists, opposition parties including Congress and AAP had asked for a proof.
