One of the civilians who died during violence in Kardampuri was hit on the head, Delhi Police said on Monday evening. The Delhi Police officer - Head Constable Rattan Lal, 42, - was killed in Chand Bagh, while a Deputy Commissioner was injured in Gokulpuri.

Several disturbing videos of the violence emerged through the day, including one late on Monday evening that showed a massive fire consuming the tire market in Gokulpuri. In other videos of the violence, which rapidly spread to Bhajanpura, Maujpur, Jaffrabad and other areas, vehicles, shops and buildings were also set ablaze. A petrol pump was set on fire in Bhajanpura as petrol bombs were thrown.

In one video a man in a red shirt can be seen running at an unarmed Delhi Police officer in Jaffrabad, where over 1,000 women began a peaceful protest on Saturday night, waving what appears to be a gun. He has been detained by the police. Other videos show people from both groups breaking off chunks from the concrete divider along the road to throw at each other. In at least one of these videos shouts of "Jai Shri Ram" can be heard.

Delhi Police initially resorted to firing tear gas shells. Once the violence escalated, paramilitary forces were called in; a Rapid Action Force (RAF) has been sent to Khajoori Khas, which is around 10 kilometres from Bhajanpura. Delhi Metro has closed the Jaffrabad, Maujpur-Babarpur, Gokulpuri, Johri Enclave and Shiv Vihar stations.

Large gatherings have been banned in northeast Delhi under Section 144. They have also been imposed outside Delhi Police Headquarters after calls for protest marches by the JNU Students Union against the "Sanghi police's brutal suppression of peaceful protests and complicity with violence unleashed... in northeast Delhi".

Delhi Chief Minister Arvind Kejriwal, who expressed sorrow at the death of the Delhi Police officer, called the violence "very distressing" and urged Union Home Minister Amit Shah - under whose control Delhi Police rolls up - to "restore law and order and ensure peace and harmony is maintained". Political analyst Yogendra Yadav also took to Twitter to raise alarm over the clashes.

Delhi Lieutenant Governor Anil Baijal said he had "instructed Delhi Police to ensure law and order is maintained". "The situation is being closely monitored. I urge everyone to exercise restraint for maintenance of peace and harmony," he said.

Government sources said the violence in the national capital appears to have been "orchestrated" by some for publicity as it comes at a time when Donald Trump is visiting the country.

The Delhi government has ordered all private and government schools to be closed in the northeast Delhi district to remain closed on Tuesday in the wake of the violence.
