French President Emmanuel Macron has postponed a trip to Germany due to begin on Sunday after a fourth night of rioting in cities across France, as family and friends prepared to bury the teenager whose killing by police unleashed the unrest.

Several hundred people lined up on Sunday to enter Nanterre’s grand mosque for the burial of Nahel M, a 17-year-old of Algerian and Moroccan descent who was shot by a police officer during a traffic stop on Tuesday in the Paris suburb.

Violent clashes continued on Friday night, despite the deployment of some 45,000 police officers backed by light armoured vehicles.

Looting and rioting took place in the cities of Lyon, Marseille and Grenoble with bands of youths pillaging shops, setting fires and pelting officers with projectiles.

France’s interior ministry said on Twitter that 1,311 people had been arrested overnight, compared with 875 the previous night, although it added the violence was “lower in intensity”.
