Right ahead of the Karnataka Bandh tomorrow, Bengaluru district administration on Thursday has announced a holiday for schools and colleges. The decision comes today as the ‘Kannada Okkuta’, an umbrella organisation for Kannada outfits, including factions of Karnataka Rakshana Vedike, Kannada Chalavali (Vatal Paksha) and various farmers’ bodies, has given a call for a statewide dawn-to-dusk shutdown on Friday to protest against the order of releasing Cauvery water to Tamil Nadu.
