Lt-Gen Aamer Riaz, Commander Army's Southern Command based in Quetta, made the remarks while talking to reporters.
"The arrest of Kulbhushan Yadav, a RAW agent, from Balochistan is an indication that India has mounted an unconventional war on us... India wants to spread chaos and anarchy in Pakistan," he claimed.
Pakistan said the alleged Indian spy was arrested in March. In a video, he had confessed planning to carry out subversive activities in Balochistan and Karachi.
General Riaz said people opposed to progress of Pakistan were hatching conspiracies.
