U.N. Secretary-General Antonio Guterres said Friday the world is not only fighting the ``common enemy'' of the coronavirus ``but our enemy is also the growing surge of misinformation'' about COVID-19 disease.

The U.N. chief said: "It is time to put armed conflict on lock down and focus together on the true fight of our lives."

UN Secretary-General Antonio Guterres also said 2018 saw more than 12,000 children killed or injured as a result of those conflicts, the highest number since 1996.

UN chief Guterres urged officials from almost 200 countries to embrace the economic opportunities that come with cutting greenhouse gases.

Unless emissions of carbon dioxide and other greenhouse gases are sharply cut, temperatures could rise to twice the threshold set in the 2015 Paris accord.

The summit, which moved to the Spanish capital after Chile had to pull out amid anti-government protests, aims to put the finishing touches to the rules governing the 2015 Paris accord.

Carney first spoke of the risks that climate change poses to to finance in 2015, and since then has urged better risk management, supervision and disclosure.

Speaking before the start Monday of a two-week international climate conference in the Spanish capital, Guterres said that ``our war against nature must stop and we know that that is possible.''

Although Myanmar and Bangladesh have a formal agreement to repatriate the refugees, none have officially returned, fearing for their safety.

UN spokesperson Stephane Dujarric said so far 129 countries had paid their dues for 2019, which amounted to almost $2 billion.
