Addressing a news conference here, Gilani said, "We are not silent on the issue. When we talk about such evidence, the timing and forum to make them public have to be determined. When there is a need, we will produce the evidence at that time."
He was responding to a question on when Pakistan would make public the evidence it has of India's alleged interference in Balochistan and the tribal belt bordering Afghanistan.
Gilani did not give details of the evidence that Pakistan has purportedly gathered.
Over the past few weeks, Pakistani civil and military officials have claimed that evidence of India's alleged role in fomenting unrest has been found by security forces and intelligence agencies.
