The Union Home Ministry said it is dispatching 15 additional companies of central forces to Haryana, as violence also erupted in Sohna in neighbouring Gurugram district, adjacent to Delhi.
As news of the violence in Muslim-dominated Nuh spread, mobs in Sohna set ablaze four vehicles and a shop, apparently belonging to people from that community. Protesters there blocked a road for hours.
About 2,500 men, women and children who had taken shelter at a Shiv temple in Nuh were evacuated by police, Haryana Home Minister Anil Vij said.
Prohibitory orders banning assembly of people were clamped in Nuh and Gurugram districts. Mobile internet services were suspended in Nuh and Faridabad up to Wednesday.
Educational institutes were ordered closed Tuesday in Faridabad and Palwal districts as a precautionary measure. Gurugram Police Commissioner Kala Ramachandran said two home guards, attached with the district, were killed in the violence in adjoining Nuh. About 10 police personnel injured in Nuh violence, the official said.
