'Now is our moment,' Obama tells Berliners

Barack Obama gave a speech to rapturous applause in Berlin today where he told the gathered crowds that "now is our moment" as he touched on subjects such as nuclear weapons and climate change.

Barack Obama was greeted as a rock star in Berlin tonight as he urged Europe and America to come together "to defeat terror and dry up the well of extremism that supports it".

His first international tour saw thousands of supporters waving American flags around Berlin's Victory Column in Tiergarten Park as they waited to catch a glimpse of the Democratic US presidential candidate.
