PARIS (AFP) - Upcoming UN climate talks in Paris will focus on the negotiations, and "a whole series" of side events will be cancelled, the French Prime Minister said on Monday (Nov 16).

Speaking three days after Paris was hit by devastating extremist attacks, Mr Manuel Valls said the city would be the "capital of the world" when the crunch climate talks kick off on Nov 30.

"No head of state, of government - on the contrary - has asked us to postpone this meeting. All want to be there," he said on RTL radio.

"To do otherwise would, I believe, be to yield to terrorism."

"France will be the capital of the world," he said, adding the conference would "probably" be reduced to the negotiation.

"We are in the process of looking at that but everything which was outside of the COP (climate talks), a whole series of concerts, of rather festive events, will be without a doubt cancelled," he added.

Islamic State in Iraq and Syria (ISIS) militants have claimed a series of coordinated attacks on Friday by gunmen and suicide bombers who killed at least 129 people in scenes of carnage at a concert hall, restaurants and the national stadium.

US President Barack Obama still intends to attend the climate talks, known by the UN acronym as COP21, a US official said on Saturday.

Mr Obama will be one of more than 115 heads of state and government expected at the conference, taking place at Le Bourget outside Paris from Nov 30 to Dec 11.

The talks aim to forge a new international pact from 2020 to curb heat-trapping greenhouse gases that stoke climate change.
