Bihar's opposition RJD has called a bandh in Saran district on Wednesday to protest the death of 20 students, mostly girls, after they consumed mid-day meal at a government primary school.
Bihar BJP has also called Chapra Bandh to protest against the deaths.
RJD President Lalu Prasad, who is Lok Sabha member from Chhapra in the district, accused the state government of being responsible for the incident and demanded a probe against a mid-day meal in this area.
The police said the victims were aged below 10 years and studied in between class I to V.
The RJD President accused "unholy nexus" between the state government and NGOs in the mid-day meal scheme here.
BJP also attacked the Nitish Kumar government with party leader Giriraj Singh charging the "Nitish government has now become more dangerous than the Lalu Prasad dispensation."
"The system has failed in the state under JD(U) government now," BJP MLA from Taraiyya Janak Singh said.
