UN Climate Summit: COP25 negotiators reach climate deal

A deal has been reached at the United Nations Climate Summit (COP25) in Spain after a two-day deadlock.

The talks were aimed at deciding how the 2015 Paris accord should be implemented.

The two-week COP25 climate summit was due to end on Friday but was extended till Sunday after negotiators made a last-ditch push to salvage an agreement to tackle global warming.
