You can hear what sounds like screams of people.

What did witnesses see – and what is local media reporting?
One witness told broadcaster BFMTV he saw first aiders working on “little bodies, three or four years old, perhaps”.
Local politician Antoine Armand said the children were attacked on a playground near a primary school.
Speaking to BFMTV from the National Assembly building in Paris, he said the victims include “very young” children who were “savagely attacked”.
BFMTV showed footage of several policemen overpowering an individual in a park.
Another witness, who gave his name as Ferdinand, told BFMTV: “He jumped (in the playground), started shouting and then went towards the strollers, repeatedly hitting the little ones with a knife.
Another witness who owns a restaurant nearby, George, said: “Mothers were crying, everybody was running.”
Yohan, who owns an ice-cream parlour opposite the park, said: “It’s a place where babysitters and parents take young children to play. I often see around 15 toddlers there in the morning, and the atmosphere is fantastic.”
What have the president and politicians said?
Emmanuel Macron said it was an “absolutely cowardly attack in a park” and the “nation is in shock”.
In Paris, politicians interrupted a debate to hold a moment of silence for the victims, BFMTV reported.
The assembly president, Yael Braun-Pivet, said: “There are some very young children who are in critical condition and I invite you to respect a minute of silence for them, for their families, and so that, we hope, the consequences of this very grave attack do not lead to the nation grieving.”
