US President Donald Trump on Saturday hailed Germany as a "treasured" ally as commemorations were held marking 30 years since the fall of the Berlin Wall.
"The Cold War has long since passed, but tyrannical regimes around the world continue to employ the oppressive tactics of Soviet-style totalitarianism," Trump said in a message from Washington.
"I congratulate the German people on the tremendous strides that have been made in reuniting their country and in rebuilding the former East Germany.
"We will continue working with Germany, one of our most treasured allies, to ensure that the flames of freedom burn as a beacon of hope and opportunity for the entire world to see."
