There were joyous celebrations in Nigeria when 21 schoolgirls were reunited with their families - more than two years after being kidnapped by militants.

Around 220 girls were kidnapped by Islamic terror group Boko Haram from their school in Chibok, north-east Nigeria, in 2014.

Last week, the group released 21 of the girls after the Red Cross and Swiss government helped broker a deal.

It is hoped that last week's release will be the first in a series over the coming weeks.

Video footage captured the moment the liberated girls were reunited with their families on Sunday amid wild celebrations.

A further 197 girls are still believed to remain in the hands of Boko Haram.
