Rebels from the Baluchistan province blew up the pipelines operated by Sui Northern Gas Pipelines, Reuters reported.
Sui emergency manager Ayub Bajwa told the news wire this was the first time all three had been blown up simultaneously.
“They used to just blow up one here or there,” Bajwa said.
He added the pipelines were 24, 18 and 16 inches in diameter, meaning it would take at least two days to repair them.
Reuters reported that a spokesman for the Baloch Republican Army had claimed responsibility for the pipeline explosion.
The Baloch Republican Army is a secessionist armed group formed to counter “the forced occupation of Balochistan”.
