"The evidence will be presented at a suitable time," Gilani told media persons at the Multan airport.
Responding to a question regarding the safety of country's nuclear installations, Gilani said Pakistan would never compromise on its nuclear programme and that the country's nuclear assets were safe under the Nuclear Command and Control Authority.
He urged the international community to help Pakistan fight the menace of terror and build its anti-terror capacity, adding Islamabad lacked state-of-the-art equipments needed to root out extremists from its soil.
Commenting on the US led drone attacks in the tribal areas in the lawless tribal areas along the Pakistan-Afghanistan border, Gilani reiterated that the missile hits were proving counterproductive in the 'war on terror'.
"While we are trying to separate militants from tribesmen, drone attacks are doing exactly the opposite," he said.
