U.S. President Barack Obama has returned home from Paris, following ceremonies on the Channel coast marking D-Day - the 65th anniversary of the allied invasion of Nazi-occupied France during World War II.

Mr. Obama joined French President Nicolas Sarkozy and other leaders Saturday at a solemn event commemorating the 1944 Allied invasion in Normandy.  Mr. Obama told those gathered at an American cemetery the world will not forget the deeds of allied soldiers on that historic day.

Mr. Sarkozy called on European nations and the United States to continue in that spirit of unity in the face of today's global threats.
Before Mr. Obama departed Paris Sunday, he and his family toured the famed Pompidou Center modern art museum.  They visited Notre Dame Cathedral Saturday evening and dined near the Eiffel Tower.

The prime ministers of Britain and Canada, Gordon Brown and Stephen Harper, and veterans of the invasion also took part in D-Day ceremonies Saturday, at an American cemetery near one of the 1944 beachheads.

More than 150,000 U.S., Canadian and British Commonwealth troops landed at and near Normandy on June 6, 1944, in a massive push to liberate Europe from the Nazi Germany.  

President Obama's trip began earlier in the week in Riyadh, Saudi Arabia.  He then traveled to Cairo, Egypt, where he called for a "new beginning" in relations between the United States and Muslims around the world.
