Police detain 100 people as Paris climate change protest 'turns violent'
About 100 people have been detained after a protest seeking a global climate deal turned violent, Paris's police chief said.
Michel Cadot told reporters that police identified about 200 or 300 people who violated a ban on all protests under the country's state of emergency.
The state of emergency was declared because of recent extremist attacks that killed 130 people in Paris.
Mr Cadot said today about 100 people who were found to have projectiles or other suspicious objects were detained.

The protesters were gathering ahead of critical global warming talks outside Paris.
