Conclusions about type of explosive will be made after the investigation, the group said.
According to Transneft, the line operator, work to repair the damaged section of the pipeline will be completed on Monday and then Caspian oil from Azerbaijan will again be delivered to terminals on the Black Sea (Novorossiisk).
