Hello and welcome to News Hour Live from the BBC World Service in London.
I'm Rebecca Kesby.
Coming up on the programme today, Dame Jane Goodall,
the groundbreaking scientist, has died at the age of 91.

And so two days later I saw two chimpanzees this time in very plain view and not only were they using grass stems to fish for termites but one of them several times picked a leafy twig and to use that he had to strip the leaves off.
That's the beginning of tool making.
And we'll have more from that interview with Jane Goodall and also we'll be assessing her legacy with the British naturalist Chris Packham in about 30 minutes time.

and that all Europeans need to understand what's at stake.
But when does a hybrid war become an actual war?
Today European leaders and defence officials met in the Danish capital Copenhagen to discuss recent drone incursions into European airspace.
They began last month in Poland, but since then Romania, Lithuania Norway,
