WASHINGTON (Reuters) - President Barack Obama has not yet decided how many troops to keep in Afghanistan after 2014, but a total pullout is one of the options under consideration, the Pentagon said on Tuesday.

Pentagon spokesman George Little, in a news briefing, declined comment on whether Defense Secretary Chuck Hagel supported keeping U.S. forces in Afghanistan after 2014, saying he would not disclose Hagel's private recommendations to Obama.
