A mob attacked a mosque in Gurugram and killed its 26-year-old naib imam, taking the toll in the violence that erupted over an attempt to stop a Vishva Hindu Parishad procession in Nuh district to five, the police said on Tuesday. The Haryana chief minister and the Opposition parties have appealed for peace in the state. The Opposition, however, blamed the BJP for the communal violence.

Authorities on Tuesday imposed a curfew in Nuh where four people were killed and many others injured on Monday. The victims are Home Guard personnel Neeraj and Gursewak, and a civilian—Shakti from Bhadas village. The identity of the fourth victim is still to be ascertained. The violence spread to neighbouring Gurugram, where a mob reached Anjuman Masjid in Sector 57 after midnight. Some people in the crowd opened fire at the people present in the mosque and also set it ablaze. The imam, identified as Saad from Bihar, died during treatment, a cop said.
