Washington: Top outgoing top American commander in Afghanistan has said that the US would keep between 6,000 and 20,000 troops in the war-torn nation after 2014.
Marine General John Allen made his recommendations to Defence Secretary Leon Panetta, but could not confirm what specific troop levels he has proposed as options.
Citing a senior military official, a report by the New York Times said that Allen gave Panetta plans for 6,000, 10,000 and 20,000 troops from which to choose for when NATO`s combat mission ends at the close of 2014.
According to the paper, Allen noted that the risk for failure decreases as the troop levels increase, CBS News reports.
The Times could not determine whether President Obama had reviewed Allen`s recommendations.
Defence officials said that Obama was expected to talk about them next week when Afghan President Hamid Karzai visits Washington.
