Investigations into the "toolkit" tweeted by teen climate activist Greta Thunberg and others in connection with the farmers' protest - a document police claim indicates a conspiracy behind the violence in Delhi on Republic Day - has "revealed a lot", Foreign Minister S Jaishankar said today. Mr Jaishankar said more details would be uncovered as Delhi Police continues its probe, and took a swipe at "some celebrities" for speaking on matters "which they obviously didn't know very much".
