A leading defence expert has said that Pakistan must be taught a lesson in its own language if found guilty of derailing trains in India.
Referring to primary indications that the accident of last year's Patna-Indore express train was caused due to rail fracture, Major General G D Bakshi (retd) said that Pakistan's Inter-Services Intelligence (ISI) can be behind the derailing of four trains.
"Terrorists keep on changing their methods for terror attacks and ISI can now be Maoist insurgents. If it is true, it's a new big challenge," Bakshi said.
He said the country has nearly 1.20 lakh-km rail tracks and cannot deploy security persons at a distance of every kilometre.
Praising the Union government and Prime Minister Narendra Modi, Gen Bakshi said last year's surgical strike in Pakistan-administered Kashmir by Indian soldiers was bold and courageous action, and Pakistan deserves more of it.
"If Pakistan is playing with the lives of Indian, the terror-supplying neighbour (Pakistan) must be taught a lesson and there should be a message for the world that Indian lives are not so cheap," he added.
