Syria conflict: Obama rules out ground troops for Syria
President Barack Obama has ruled out deploying US ground troops in Syria and says military efforts alone cannot solve the country's problems.
"It would be a mistake for the United States, or Great Britain... to send in ground troops and overthrow the [Bashar] Assad regime," he told the BBC.
He also said he did not think so-called Daesh would be defeated in his last nine months of office.
But he said: "We can slowly shrink the environment in which they operate."
