Police say 19 people have been killed, including 11 when cooking gas cylinders blew up, during clashes with residents who were being evicted from illegally occupied government land in northern India.

Top state police officer Daljit Chaudhary says two police officers were among those killed as some from a crowd of 3,000 protesters fired at them Thursday in Mathura, a town 300 kilometers (200 miles) southwest of Lucknow, the capital of Uttar Pradesh state.

Chaudhry said Friday that the police had gone to a district in the town to retake land from illegal occupiers following a court order.

Police said some people died from police fire, but 11 deaths occurred when the gas cylinders burst and set fire to the area.
