Facebook Messenger 'slims down'
Facebook has announced a "slimmed down" version of its Messenger app for countries where older smartphones and slower net speeds are more common.
The company said Messenger Lite had the "core features" of the full app such as the ability to share text and photos.
The BBC's Chris Foxx asked Facebook's Stan Chudnovsky why the company had two competing message services - WhatsApp and Messenger.
