The US Secretary of State Hillary Clinton has announced a global partnership to tackle the scourge of toxic smoke from indoor cooking fires.
Cooking smoke is estimated to shorten the lives of 1.9 million people a year; it also contributes to climate change.
The Global Alliance for Clean Cookstoves is a partnership between the US government and other nations along with charitable foundations.
It is believed to be the first major attempt to tackle the issue worldwide.
The project will attempt to build on national programmes already underway in India, Mexico and Peru.
