A celebration of a local election win in the Turkish city of Denizli turned deadly for Türkiye’s Republican People’s Party (CHP), with one person killed and seven others injured.

The accident occurred overnight as party members and supporters gathered to celebrate the victory of Kadir Tatik in his campaign for the local municipality head’s office, after preliminary results of the election were announced.

Footage from the scene shows multiple party members gathered on a balcony of a building, with a crowd of onlookers cheering them on outside. The balcony is seen abruptly collapsing, coming clean off the rest of the structure.
