US holding "constructive talks" with groups in Afghanistan: Trump

President Donald Trump said on Tuesday his administration was holding "constructive talks" with groups in Afghanistan, including the Taliban, and would be able to reduce the U.S. troop presence and focus on counter-terrorism as it makes progress.

"We do not know whether we will achieve an agreement - but we do know that after two decades of war, the hour has come to at least try for peace," Trump said in his annual State of the Union address.
