Ebola outbreak in DRC 'growing exponentially'

The Ebola outbreak in the Democratic Republic of Congo is growing exponentially, with more than 2,500 deaths reported.

The UN warns it is the biggest outbreak in the country's history, spreading faster than any on record.

The DRC has received 70,000 Ervebo vaccine doses, but challenges remain in reaching affected areas.

Health workers are also under attack, complicating the response.
