Several thousand people have gathered at the biggest of Berlin's Soviet war memorials to mark the surrender of Nazi Germany, among them Russia's ambassador and bikers wearing the colors of the nationalist Night Wolves group.

Some carrying Russian or Soviet flags, people laid flowers at the huge memorial in Berlin's Treptow district. It includes a mausoleum topped by the figure of a soldier standing on a shattered swastika.

The pro-Kremlin Night Wolves' plans to ride from Moscow to Berlin to commemorate the 70th anniversary of the war's end in Europe prompted controversy, particularly in Poland where officials denied them entry. German courts, however, ruled there was no legal reason to keep them away.

Bikers apparently from the group laid carnations Friday at the site where Nazi Germany's surrender was signed.
