Event thrown into confusion and 13 treated for smoke inhalation after conference centre evacuated

• Brazilian president will take fossil fuel phase-out plan to G20 summit

Talks at the Cop30 climate summit in Brazil were disrupted on Thursday after a fire broke out in the venue, triggering an evacuation just as negotiators were preparing to try to land a deal to strengthen international efforts to address the climate crisis.

Thirteen people were treated for smoke inhalation, organisers said in a statement, after the fire broke out in the pavilion area of the conference centre in Belém, Brazil.
