Twin mountain gorillas have been born in Volcanoes National Park in Rwanda.
The babies born on 3 February 2011 are only the fifth set of twins ever recorded in the history of Rwanda's mountain gorillas.
The last reported birth of mountain gorilla twins was in 2004, according to conservation group The Gorilla Organization.
Fewer than 800 mountain gorillas are thought to remain in the wild, though numbers are thought to be increasing.
It is very rare to hear of mountain gorilla twins, so we were all excited to hear the news from rangers yesterday, says Emmanuel Bugingo, Programme Manager in Rwanda for The Gorilla Organization, which has staff in London, UK and Africa.
