The Hague: Pakistan on Tuesday responded to India at the International Court of Justice (ICJ) in the case of Kulbhushan Jadhav, insisting that the ex-Indian Navy officer was a "spy" and not a businessman.

The four-day hearing in the Jadhav case opened on Monday at the UN court headquarters in The Hague amidst heightened tensions between India and Pakistan following one of the worst terror attacks in Jammu and Kashmir by Pakistan-based Jaish-e-Mohammad terror group that killed at least 49 CRPF soldiers.
