Chandigarh: Two days after a Punjab Police probe revealed use of drones to deliver weapons from across the border, Chief Minister Amarinder Singh on Tuesday said this has added a "new and serious dimension on Pakistan's sinister designs" after abrogation of special status to Jammu and Kashmir.

He urged Union Home Minister Amit Shah to handle the "drone problem" at the earliest. The Punjab Police on Sunday had claimed to have busted a terror module of the Khalistan Zindabad Force (KZF), backed by a group based in Pakistan and Germany. It said the terror group was conspiring to unleash a series of strikes in Punjab and adjoining states. Initial investigation revealed use of drones to deliver weapons and communication hardware from across the border.
