World leaders reach deal on climate change

World leaders have struck a deal to fight climate change after tense negotiations in Copenhagen. The breakthrough ended a deadlock at the UN-led talks. But US President Barack Obama said on Friday that the world still had "much further to go" in the fight against global warming.

The deal described by Obama reflects some progress helping developing nations cope with climate change. All countries agreed that efforts should contain global temperatures to targets set at a conference of the leading economic nations last July.

Obama suggested Friday's agreement among the five key countries would be adopted by the larger summit in its closing hours.
