In an emotive speech in Berlin US presidential candidate Barack Obama has urged Europe to stand by America in a range of challenges facing the allies.
He was given a rapturous welcome by tens of thousands of Berliners after talks earlier with Chancellor Angela Merkel.
In his speech he touched on terrorism, nuclear proliferation and global warming.
“In this new century Americans and Europeans alike will be required to do more not less,” he told the crowd. “Partnership and cooperation among nations is not a choice, it is the only way, the one way to protect our common security and advance our common humanity.”
Germany was the latest stop in Obama’s overseas tour aimed at boosting his foreign policy credentials among voters back home.
They will choose between the Illinois Senator and his Republican rival, John McCain in November’s election.
Before arriving in Germany Obama’s trip had taken him to Afghanistan, Iraq and the Middle East.
