The U.N. Security Council today (20 November) unanimously approved a French-sponsored resolution calling on all nations to unite in the fight against Isis. A UN resolution was passed calling for decisive action against the "unprecedented threat" of The Islamic State by "all means" necessary.

The decision to back the French call for "international mobilisation" against IS comes exactly one week after militants launched coordinated gun and bomb attacks in the French capital, killing 130 people.

A spate of atrocities committed by IS, including the downing of the Russian passenger jet over the Sinai Peninsula have galvanised the formerly divided Security Council, as the world powers agreed to coordinate efforts aimed at preventing further atttacks by the terror group.

The resolution adopted by the UN Security Council said IS "constitutes a global and unprecedented threat to international peace and security". It expressed the council's determination "to combat by all means this unprecedented threat".

Following the vote, in an official statement Prime Minister David Cameron said: "This is an important moment. Today, the world has united against ISIL. The international community has come together and has resolved to defeat this evil, which threatens people of every country and every religion. The United Nations Security Council has unanimously backed action against this evil death cult in both Syria and Iraq.

"It has also reiterated its determination to secure a political solution to the conflict in Syria. Today's vote shows beyond doubt the breadth of international support for doing more in Syria and for decisive action to eradicate ISIL. Britain will continue to support our allies who are fighting ISIL in Syria.

"I will continue to make the case for us to do more and to build support in Parliament for the action that I believe is necessary for Britain to take to protect our own security, as part of a determined international strategy. We cannot expect others to shoulder the burdens and the risks of protecting this country."

The UN announcement will give David Cameron the leverage to get a Commons vote through, supporting British airstrikes on Isis, Sky News reports.

France's ambassador to the UN, François Delattre said the resolution "is short, strong, and focused on one primary goal: the fight against the common enemy, Daesh [Isis]. We intend to work with all our Security Council partners to achieve a swift adoption of this project, around which we hope the international community will come together."

Syria's UN Ambassador, Bashar Ja'afari, stated prior to Friday's vote that this resolution was long overdue. "Welcome to everybody who finally woke up and joined the club of combating terrorists."

Meanwhile, Russia, as expected, did not exercise its right to veto the resolution and is instead continuing its work on a draft resolution proposing international military campaigns to fight against Islamic State. Russia's Ambassador to the UN, Vitaly Churkin, said that Moscow is working towards having the draft resolution passed soon.

The measure is the 14th terrorism-related resolution adopted by the U.N.'s most powerful body since 1999.

The vote comes as the global threat posed by extremists was highlighted after gunmen stormed a luxury hotel in Mali, which left at least 27 people dead. In the aftermath of the attack, the government in Mali has declared a ten day state of emergency.

As the UN's announcement was made, hundreds gathered around the Place De Republique in Paris, in silent vigils and moving tributes to the 130 victims of the terror attacks that left the world reeling.
