A day after the Railways sought a CBI probe into the Odisha train tragedy, Congress President Mallikarjun Kharge on Monday wrote to Prime Minister Narendra Modi, saying the agency is meant to investigate crimes, not railway accidents, and cannot fix accountability for technical, institutional and political failures.

Kharge also said “all the empty safety claims” of the rail minister have been “exposed” and the government must bring to light the real reasons that caused this grave accident, which he described as one of the worst in Indian history.
