The US is planning measures to screen incoming air passengers for Ebola, President Barack Obama has said.

The likelihood of an Ebola outbreak in the US is "extremely low", Mr Obama said, but "we don't have a lot of margin of error".

More than 3,400 people have died in West Africa in the world's deadliest outbreak of the viral disease.

Mr Obama's comments came six days after a Liberian man became the first case of Ebola diagnosed on American soil.
