"We are still waiting India's response on the matter. The Foreign Ministry had written to India several months ago and even sent reminders but the Indian government has not responded to us," a prosecution official told Islamabad Anti- Terrorism Court hearing the case at Adiala Jail in Rawalpindi.
The official informed the court that Pakistan's Director General, South Asia, had also taken up the matter with India of sending the 24 Indian witnesses to Pakistan to record their statements so that the trial is completed at the earliest.
The official said the case cannot move forward unless India sends the witnesses here to record their statements.
"We are going to send another reminder to India asking it either to send the witnesses or refuse. If India wants early conclusion of the Mumbai case, it will have to send its witnesses here," he said.
