WASHINGTON, May 6 (Reuters) - Barack Obama and Hillary Clinton appeared headed to a split in crucial presidential contests in Indiana and North Carolina on Tuesday, pushing Obama closer to securing the Democratic nomination but keeping Clinton's hopes alive.

CBS News projected a Clinton win in Indiana, which would preserve her slender chances in a prolonged Democratic duel that now moves to the next contest in one week in West Virginia.

Three hours after the CBS projection, other networks had not made a call with 86 percent of the vote counted and Clinton leading 52 percent to 48 percent.
