The UN says a record 6.9 million people are now internally displaced within the Democratic Republic of Congo due to escalating violence.

The UN's International Organization for Migration has collected tracking data from all 26 of the country's provinces.

It says the vast majority of those displaced live in the east where conflict is cited as the primary cause.

In North Kivu alone, up to a million people have fled their homes this year due to the ongoing fighting with M23 rebels.

It warns that DR Congo is facing one of the world's biggest displacement and humanitarian crises.
