Exhaust fumes from diesel engines do cause cancer, a panel of experts working for the World Health Organization says.

It concluded that the exhausts were definitely a cause of lung cancer and may also cause tumours in the bladder.

It based the findings on research in high-risk workers such as miners, railway workers and truck drivers.

However, the panel said everyone should try to reduce their exposure to diesel exhaust fumes.
