The cause of it was the accident on the gas pipeline.
Gazprom said that Azerbaijan suspended gas supplies to Russia for three days in connection with the repair works on the Shirvanovka gas metering station of Mozdok-Kazimagomed trunk pipeline due to gas leak.
Gazprom has been suppling gas from Azerbaijan since 2010, APA reports quoting “RIA Novosti”. Russia purchased 1,6 bcm gas last year.
