Sangke language
Sangke is a Skou language or dialect, spoken in Sangke Village, East Arso District, Keerom Regency in Papua Province, Indonesia. Speakers of the Wutung language report that it is similar to their language, but it's not clear what the relationship is or if it might be a dialect.
Being on opposite sides of the international border, Sangke and Wutung have been covered by different surveys and comparative work has not been done.
