CIA warned Germany about Nord Stream pipeline attack

Der Spiegel (https://bit.ly/3Ea4QFB), one of Germany's premier
magazines, claims that the Central Intelligence Agency (CIA) warned
about a possible attack on the Nord Stream gas pipelines from Russia
just days before it happened.
Citing unnamed sources, Der Spiegel says the CIA tipped off Berlin
about a potential sabotage incident that would bring both Nord
Stream 1 (NS1) and Nord Stream 2 (NS2) offline.
"CIA warned Germany weeks ago of coming attack on natural gas
pipelines Nord Stream I & II (from Russia to Germany)," tweeted
American author and co-founder of the Breakthrough Institute,
Michael Shellenberger.
"Russia could have pulled off such an attack but ‘It is difficult to
see whether Russia or Ukraine could have an interest in such an
incident," he added, citing the Der Spiegel report.
The article goes on to speculate that from Ukraine's point of view,
a "permanent interruption" of gas from Russia to Germany could be
"a possible interest in the room."
"On the contrary," the article adds, "there would be immense
political disadvantages that could arise from an attack."
Denmark, has like other countries in the region, raised its safety
level for its power and gas sector after several countries said two
Russian pipelines to Europe spewing gas into the Baltic Sea had
been attacked. "There have been observations of unauthorized
drone activity (https://reut.rs/3BW7vQG) at the Halfdan B oil and
gas field in the North Sea," a spokesperson said in a written
comment, adding the activity had been observed on Wednesday.
"We have taken the necessary steps in accordance with our security
procedures and are in close dialogue with the authorities."
