The European Parliament demanded that construction on the controversial Nord Stream 2 pipeline be halted, DW reports.
It issued the call in response to Russia arresting opposition figure Alexei Navalny upon his return to Russia. He had been in Germany recovering from an attempted assassination with a military grade nerve agent.
Nord Stream 2 will transport natural gas from Russia to Germany, and will double the capacity of an existing pipeline. The €10 billion (roughly $11 billion) Baltic Sea pipeline is about 90% finished, but has attracted considerable criticism and divided the European Union.
"The European Parliament ... calls on the EU and its member states to critically review cooperation with Russia in various foreign policy platforms and on projects such as Nord Stream 2, the completion of which the EU must stop immediately," the resolution said.
Lawmakers voted overwhelmingly in favor of the nonbinding resolution, with 581 votes in favor, 50 against and 44 abstentions.
The resolution also calls for sanctions on Russian President Vladimir Putin's inner circle as well as the Russian officials behind the arrest of Navalny. It stressed that "Russian wealth of unclear origin should not be welcome in the EU."
It calls for the immediate release of Navalny and his colleagues.
After the resolution passed, Russian authorities arrested more associates of Navalny, including his spokeswoman, Kira Yarmysh, who was seated next to him on his almost fatal flight from Tomsk.
