Participants of a UN environmental meeting in Kenya's capital, Nairobi, are mourning the loss of delegates who were on the crashed Ethiopian Airlines plane.

The UN Environmental programme described the deaths as a "terrible loss":

"The environmental community is in mourning today. Many of those that lost their lives were en-route to provide support and participate in the UN Environment Assembly. We lost UN staff, youth delegates travelling to the Assembly, seasoned scientists, members of academia and other partners," it said in a statement.
