US Senator Barack Obama won enough delegates to secure the Democratic nomination for president, according to US media projections.
'Our contest has finally come to an end', Mr Obama said in a victory speech in St Paul, Minnesota.
He will be the first major party African-American nominee in that country's history.The projection came just moments after polls closed in South Dakota. While Senator Hillary Clinton won in that high plains state, Mr Obama received a share of the delegates he needed to put him over the top.
