India mourns the loss of Dr. Manmohan Singh, former Prime Minister and one of its most transformative leaders. Known for liberalizing India's economy as Finance Minister, advancing the India-US nuclear deal, and ushering in landmark legislations like the Right to Information and Right to Education, Dr. Singh's legacy spans decades of public service. World leaders have paid heartfelt tributes to the 92-year-old statesman. In another development, Russian air-defence systems are believed to have shot down an Azerbaijan Airlines plane, leading to the tragic death of at least 38 people. The flight was en route from Azerbaijan's capital Baku to Grozny in southern Russia before veering off course. The plane crashed into Kazakhstan after an emergency, with Russian aviation authorities citing a potential bird strike. Watch NDTV'S The World Report for the latest updates.
