The Netherlands will tighten security at its borders and airports following the attacks in Paris, Dutch Prime Minister Mark Rutte said on Saturday, adding the Dutch were "at war" with Islamic State, which claimed the attacks.

Speaking to reporters, Rutte said all traffic to and from France and Paris would be closely monitored, including at airports and railways stations. All security services were working at a heightened level of preparedness, he added.

"Our values and our rule of law are stronger than their fanaticism," he said. "ISIS (Islamic State) is our enemy. We are at war with ISIS. We are not at war with a country, a belief or with Islam."

Meanwhile, the French government plans to go ahead with a climate change summit it is due to host at the end of the month, a senior French diplomatic source said on Saturday.

Asked whether the high-profile meeting could be put off, the venue changed or canceled, the source told Reuters "that is in no way under consideration," but added that security could be boosted.

Officials from almost 200 nations are due to meet from Nov. 30 to Dec. 11 to nail down a final agreement to limit global warming.
