Prime Minister Narendra Modi on Thursday changed the display pictures on his social media handles to mark the one year of the Operation Sindoor, which started this day a year ago. The profile picture of PM Modi on his handles on X, Facebook, Instagram and WhatsApp channel have been changed to an image with the text 'Operation Sindoor' on a black background. The picture has a tricolour, with one of the 'O's of 'SINDOOR' filled with vermilion or sindoor -- a symbol of married Hindu women.
