On Tuesday, an organizer said that amid worries over security post attacks that killed 129 people, France is going to take a decision in coming couple of days on whether or not to allow climate change activists to stage a rally in Paris on the eve of a UN summit on November 29.

Despite the attacks that have been claimed by Islamic State militants, campaigners went to meet French Foreign Minister Laurent Fabius, who will be the host of the November 30-Decemebr 11 summit, for putting their case for the march in central Paris.

Speaking to Reuters, Eros Sana, an organizer at the environmental activist group 350.org, said the government ‘will respond to them on Wednesday evening or Thursday regarding the security and logistics’.

350.org and nearly 130 other organizations that include labor unions and faith groups have come together and have been looking forward to organize one of the biggest climate change rallies in history, competing one held in New York in 2014 that as per the organizers attracted 310,000 people.

Over the weekend, France reaffirmed that the summit will take place but on Monday, Prime Minister Manuel Valls spoke otherwise.

On Monday, a meeting was held wherein organizers decided to try to find out a way to hold the demonstration. They also motivated people worldwide to participate in the marches in cities from Sydney to London.
