A pressure gauge is seen at the landfall facility of the Baltic Sea gas pipeline Nord Stream 2 in Lubmin, Germany, September 19, 2022.
"Overnight the Nord Stream 2 landfall dispatcher registered a rapid gas pressure drop on Line A of the Nord Stream 2 natural gas pipeline," Nord Stream 2's operator said in a statement.
European countries have resisted Russian calls to allow the Nord Stream 2 pipeline to operate and accused Moscow of using energy as a weapon.
Gazprom (GAZP.MM) referred questions about the incident to the Nord Stream 2 operator.
Russia has cut off gas supplies to several countries and also halted flows through the Nord Stream 1 pipeline, blaming Western sanctions for hindering operations.
