Adani Group said the report on the business house was a "calculated attack" on the country and its institutions while a senior executive compared a rout of its stocks with a colonial-era massacre.

The short seller report has cast doubts on how investors will respond to the company's record $2.45 billion secondary sale.

U.S. dollar-denominated bonds issued by Adani Sport and Special Economic Zone continued their fall into a second week with the bond maturing in August 2027 down 5 cents to 73.03 cents, the lowest since June 2020.

International bonds issued by Adani Green Energy, Adani Economic Zone, Adani Transmission and Adani Electricity Mumbai also fell.
