Congress leader Shaktisinh Gohil has said Prime Minister Narendra Modi should break his silence and answers the issues raised by former Army chief General (retd) Shankar Roychowdhury over the 2019 Pulwama terror attack. "Gen (retd) Shankar Roychowdhury said the biggest responsibility for the martyrdom of soldiers in Pulwama rests with the government. The National Security Advisor, who advises the prime minister, is also guilty of lapses in security," Gohil, a Rajya Sabha MP, said on Saturday.
