'Visionary' leadership needed on TB

Many first-choice antibiotics no longer work against some
 strains of the tuberculosis bacterium

Plans to tackle tuberculosis are failing and a new visionary approach is needed, according to an international group of doctors and scientists.

There is mounting concern that a rise in "virtually untreatable" tuberculosis poses a threat to countries around the world.

Writing in the Lancet medical journal, the group said governments were "complacent" and "neglectful".

It called for countries to do more to tackle the problem.

The World Health Organization says nearly nine million people become sick and 1.4 million die from tuberculosis each year.
