Obama, Karzai accelerate end of U.S. combat role in Afghanistan

WASHINGTON (Reuters) - President Barack Obama and Afghan President Hamid Karzai agreed on Friday to speed up the handover of combat operations in Afghanistan to Afghan forces, raising the prospect of an accelerated U.S. withdrawal from the country and underscoring Obama's determination to wind down a long, unpopular war.

Signalling a narrowing of differences, Karzai appeared to give ground in talks at the White House on U.S. demands for immunity from prosecution for any U.S. troops who stay in Afghanistan beyond 2014, a concession that could allow Obama to keep at least a small residual force there.
