White House hopeful Barack Obama has landed in Berlin to begin the European leg of his international tour, ahead of November's US presidential poll.
The Democratic senator is meeting Chancellor Angela Merkel, Foreign Minister Frank-Walter Steinmeier and Berlin's Mayor Klaus Wowereit.
Tens of thousands of people are expected to gather later when he makes the only public speech of his tour.
Mr Obama, 46, is due to visit France on Friday and Britain on Saturday.
The BBC's Steve Rosenberg, in Berlin, says the Illinois senator is very popular in Germany, where surveys suggest three-quarters of people want him to be the next US president.
He says Mr Obama will be hoping that once TV pictures of him addressing cheering crowds of Berliners have been beamed back to America it will boost his image as an international statesman, and his chances of beating Republican rival John McCain this autumn.
