Environmental and other activists are lining up shoes on Paris streets and holding a healing ceremony to urge world leaders to reach a deal to slow climate change.

A big activists' march Sunday was banned because of a state of emergency imposed in France after Nov. 13 extremist attacks that killed 130 people.

The shoes include those of United Nations secretary general Ban Ki-Moon.

Instead, environmental groups are holding marches outside France this weekend, and some activists lined up shoes on the Place de la Republique square to represent the people barred from protesting.

Tribal leaders from different indigenous groups around the world are also planning a healing ceremony Sunday near the site of the Paris attacks.

They are urging leaders gathering for U.N. climate talks near Paris Nov. 30-Dec. 11 to agree to deep emissions cuts and to help poor countries cope with global warming.

More than 140 world leaders are gathering in Paris for high-stakes talks seeking a long-term deal to slow man-made global warming.

U.N. Secretary-General Ban Ki-moon is meeting French President Francois Hollande on Sunday morning to discuss the talks, and U.S. President Barack Obama is among scores of other leaders arriving for the talks.

The Nov. 30- Dec. 11 U.N. climate conference is under extra-high security after extremists killed 130 people around Paris earlier this month.

Negotiators from 196 countries are seeking an accord that reduces man-made emissions to limit rising sea levels and increasingly extreme weather that is already threatening populations around the world.
