Nineteen of the 23 children who died after eating a tainted free school meal in India's Bihar state have been buried in and around the school grounds.

Angry parents say they want the graves to serve as a reminder that the children died due to state negligence.

A doctor at the local hospital said a chemical used in pesticides was the likely cause of contamination.

In all, 47 primary school children fell ill after consuming the meal of rice and soybeans on Tuesday.

Twenty-two were confirmed dead on Wednesday. A day later Bihar's Principal Secretary Amarjeet Singh confirmed another of the children had died.

Officials say the headmistress of the government school, in the village of Dharmasati Gandaman in Saran district, has fled.

Some children at other schools in the state are now reported to be refusing to eat the free meal.

"We have received complaints that children in some schools in four or five districts have refused to eat the midday meal. We are trying to resolve the issue," Mr Laxamanan, the director of the Mid-Day Meal scheme in Bihar, told the BBC.

The scheme provides free food for students, but often suffers poor hygiene.

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.

'Government's negligence'

Angry parents and villagers have buried three children inside the school campus while 16 others have been buried in a nearby area, Patna-based journalist Amarnath Tewary reports from Dharmasati Gandaman.

"People must not ever forget that our children died inside the school because of the government's negligence," Rangeela Prasad Yadav, whose 11-year-old grand-daughter Mamata was among the dead, told the BBC.

More than 100 people from the surrounding villages have attended the funerals and many are still standing around, mourning their loss.

Inside the school, books are strewn around and the kitchen where the deadly meal was cooked has been demolished by angry villagers.

On Wednesday, hundreds of parents and villagers protested by setting four police vehicles on fire.

Armed with poles and sticks, they blocked streets and locked railway gates, halting the movement of trains.

As well as the protests in Dharmasati Gandaman, a crowd set fire to a bus and damaged private property in the nearby town of Chhapra.

Officials said the children showed symptoms of poisoning by organo-phosphorus, a compound also used as a pesticide for crops.

Bihar State Education Minister PK Shahi told a news conference the cook told him the school had bought a new type of cooking oil and she thought the oil looked "discoloured and dodgy".

She drew it to the attention of the headmistress - who was in charge of the Mid-Day Meal Scheme at the school and had been transferred there recently - who said the "oil was home-made and safe to use".

The minister said the oil had been bought from the grocery store run by the husband of the headmistress.

Mr Shahi said the grocery store owner and other men in his family had fled.

An inquiry has begun and 200,000 rupees ($3,370) in compensation has been offered to the families of each of those who died.

Bihar is one of India's poorest and most populous states.
