Violence has broken out in India's technology hub Bangalore in Karnataka state over a long-running dispute about water. Protesters are angry at a Supreme Court ruling ordering Karnataka to share water from the Cauvery river with neighbouring Tamil Nadu. TS Sudhir reports on the latest crisis.

By dusk, dark smoke had filled the Bangalore skies. Some 35 buses had been set on fire by protesters, just because the buses belonged to an travel agency whose owner is Tamil.

The main city of Bangalore is the worst affected: the violence in the technology hub forced the closure of many offices and much of the public transport system. Police have imposed an emergency law that prohibits public gatherings, and more than 15,000 officers have been deployed across the city.

One person was killed when police opened fire on protesters on Monday evening. Buses and trucks bearing Tamil Nadu number plates have been attacked and set on fire. Schools and colleges are closing early and many businesses are shut.

Across the border, in Tamil Nadu, petrol bombs were hurled at a popular restaurant owned by a resident of Karnataka in Chennai while the driver of a vehicle with Karnataka number plates was slapped and ordered to say "Cauvery belongs to Tamil Nadu".
