Ukraine's state energy firm Naftogaz has no power to halt the Nord Stream 2 pipeline being built between Russia and Germany, despite its role in the certification process, while its own transit deal with Russia may not be renewed, Naftogaz head Yuriy Vitrenko told Reuters on Monday.
Gunmen have killed four men who were involved in the maintenance on a pipeline owned by the Nigerian subsidiary of Italian oil giant Eni, a local security spokesman told Reuters.
Germany said on Sunday it was continuing to work closely with the United States on implementing a deal on the Nord Stream 2 pipeline, which runs under the Baltic Sea and carries gas from Russia to Germany.
Italian energy group Eni has agreed to sell gas group Snam 49.9% of its stake in strategic pipelines carrying Algerian gas into Italy for 385 million euros ($436 million), the two companies said on Saturday.
Australia on Friday outlined a plan to spur investment in new gas pipelines to beef up gas supply, despite the government's pledge to achieve net zero carbon emissions by 2050 in the fight against climate change.
