Updates on the US elections.
In a surprise development, New York Mayor Michael Bloomberg has endorsed US President Barack Obama who is seeking re-election.

Obama is pitched against Mitt Romney, the Republican presidential candidate, for the November 6 elections; which according to political analysts is a very close race.

In such a scenario an endorsement of the powerful Mayor of New York City could add to his advantage, they say.

In his endorsement, Bloomberg cited Obama's view and stance on climate change as one of the key reasons for his decisions. "Our climate is changing. And while the increase in extreme weather we have experienced in New York City and around the world may or may not be the result of it, the risk that it might be -- given this week's devastation -- should compel all elected leaders to take immediate action," he said. "But we can't do it alone. We need leadership from the White House -- and over the past four years, President Barack Obama has taken major steps to reduce our carbon consumption, including setting higher fuel-efficiency standards for cars and trucks," he added.

Obama in a statement said he is honoured to have Bloomberg's endorsement.
