Eagle Woman and Dallas Goldtooth led a healing ceremony in front of thousands outside the Bataclan Theatre in Paris where many lost their lives in the recent attacks.
It took place as COP21 climate talks commenced in the city. An Indigenous delegation traveled there to generate awareness about how climate change impacts them and impart traditional knowledge.
Eagle Woman told a video produced by the New Internationalist and Films for Action that ceremony participants wanted to stand in solidarity with people.
She said they wanted to "let them know that we're here and we care, and to send a message of love and hope and peace for their future".

Dallas Goldtooth said Indigenous people could empathise with those grieving as they had experienced the impact of colonisation.
"We understand what it means to have great loss," he said.
Eagle Woman and Goldtooth said the only way for the planet to experience peace and health was to overhaul systems.
"We're fighting for a systems change, and it will happen," Eagle Woman said.
"Our delegations always see it as a necessity to have prayer before any large action," the network said via Facebook on Tuesday. "We offered kind words, song, and calls for climate justice and peace."
The ceremony was organised by the Indigenous Environmental Network. Indigenous people from North America, the Arctic and the Pacific Islands took part.
The United Nations Framework Convention on Climate Change, also referred to as Paris 2015 or COP21 is a conference being held in December in Paris towards the effort to minimise the amount of carbon dioxide released into the atmosphere.
