Fire dis­rupt­ed Unit­ed Na­tions cli­mate talks in Brazil on Thurs­day, forc­ing evac­u­a­tions of sev­er­al build­ings and de­lay­ing al­ready slug­gish ne­go­ti­a­tions by most of a day with no ma­jor agree­ments even close. Of­fi­cials said 13 peo­ple were treat­ed for smoke in­hala­tion.

The fire erupt­ed in an area of pavil­ions where side­line events are held dur­ing the an­nu­al talks, known this year as COP30. The fire was quick­ly brought un­der con­trol, but fire of­fi­cials or­dered the en­tire site evac­u­at­ed for safe­ty checks and it wasn’t clear when con­fer­ence busi­ness would re­sume.

The fire could cost sig­nif­i­cant time if the talks don’t re­sume un­til Fri­day’s sched­uled fi­nal day. The pres­i­den­cy of the talks had planned to have min­is­ters and diplo­mats work late Thurs­day.
