India students beat Bihar teachers over school lunches
Students from a government-run school in India's Bihar state have beaten up their teachers in protest at what they say is the poor quality of their lunch.

More than 100 students from a school in Bhikhampur village visited a government office to protest against the quality of the Mid-Day meal.
The teachers were assaulted when they came to give their side of the story.
On Tuesday, 47 primary school children in the village of Dharmasati Gandaman in Saran district fell ill after consuming the contaminated meal of rice and soybeans.
Twenty-three died and many others are still in hospital.
A chemical used in pesticides is a possible cause of contamination. The results of forensic tests are expected from a laboratory in the state.

It was introduced to combat hunger and boost school attendance, and reaches 120 million children in 1.2 million schools across the country, according to the government.
In Friday's incident, more than 100 students, carrying placards and shouting slogans, gathered outside the office of the Nawada district magistrate, journalist Amarnath Tewary reports from the state capital, Patna.

Nineteen of the children have been buried in and around the school grounds - families say they want the graves to serve as a reminder that the children died due to state negligence.
