At least 3.7 million people marched against extremism across France on Sunday in the biggest mobilisation ever recorded in the country, the interior ministry said.
In Paris, up to 1.6 million took part in a mammoth procession in memory of the 17 victims of Islamist killings, but it was difficult to give an exact number due to the magnitude of the demonstration, it said. Outside the French capital, more than 2.5 million joined the rallies.
