Senior Congress leader Digvijaya Singh today raised questions on the 2019 Pulwama terror attack, in which more than 40 security personnel were killed and said the Centre had given no proof of the surgical strikes against Pakistan. "Pulwama has been a hotbed of terrorism and every car is checked. A Scorpio car comes from the wrong side. Why was there no checking? Then there is a collision and 40 of our jawans are killed. To date, the government has not given information about the incident in parliament or in public," said Digvijaya Singh.
