During a visit to Washington, Foreign Secretary Aizaz Ahmad Chaudhary had said that Pakistan had evidence of India's involvement in such activities, Dawn reported from Washington.
"I am not aware of any such delivery," US State Department spokesman John Kirby was quoted as saying when he was asked at a news briefing if Pakistan had shared any proofs with the US.
Kirby, however, refused to comment on India's claim that it had evidence to prove that Pakistan was involved in terrorist attacks inside India.
He urged both countries to resolve their differences peacefully.
"We want tensions between India and Pakistan to be reduced. We want them to work together bilaterally to resolve some of these differences," he said.
