The World Health Organization has said it is monitoring a new coronavirus variant known as "Mu", which was first identified in Colombia in January.
Mu, known scientifically as B.1.621, has been classified as a "variant of interest", the global health body said Tuesday in its weekly pandemic bulletin.
The WHO said the variant has mutations that indicate a risk of resistance to vaccines and stressed that further studies were needed to better understand it.
