The UN climate talks COP30 have been evacuated due to a fire breaking out inside the venue in Belem, Brazil.
BBC journalists saw flames and smoke in the pavilion area before they were rushed outside. It is not yet known what caused the blaze.
A woman was taken away in a wheelchair, but it is not clear if that was connected to the fire.
Thousands of people are attending the UN climate talks, including members of delegations from around the world.
