Germany has taken a step closer to gas rationing after a drop in supplies from Russia.
The country has triggered the "alarm" stage of an emergency gas plan to deal with shortages, Germany's economy ministry said.
It is the latest part of a standoff between the European Union and Russia over its invasion of Ukraine.
German economy minister Robert Habeck said Russia was using gas "as a weapon" in response to EU sanctions.
"We must not fool ourselves. The cut in gas supplies is an economic attack on us by [Russian President Vladimir] Putin," Mr Habeck said, adding Germans would have to reduce consumption.
Mr Habeck said there would "hopefully never" be a need to ration gas for German industry, but he added: "Of course, I can't rule it out."
Russia has already cut gas supplies to Poland, Bulgaria, the Netherlands, Denmark and Finland over their refusal to comply with a new payment scheme.
