Three days have passed since this tragic incident. Yet, there has been no public statement at all or even a condolence message from PM Narendra Modi. The nation was waiting for it, Modiji. You spoke about 'not allowing the nation to bow', but no proof is now required that you have belittled India's global standing and sovereignty," Kharge said.Targeting the prime minister over the incident and by referring to the US statement that any violation of its blockade in the Strait of Hormuz and "illicit" transport of Iranian oil will not be tolerated, Gandhi said: "Just days after three Indian sailors were killed in American attacks there is neither regret nor apology. On the contrary, the US continues to issue orders... A sovereign nation would never tolerate such language. But our compromised PM? Silent. He listens like an obedient servant and complies with the orders."
