headlines: Russia-Ukraine war update: what we know on day 137 of the invasion
articles: Canada has granted a sanctions exemption to allow a repaired Russian turbine to be sent back to Germany for the Nord Stream 1 gas pipeline. The Canadian government said the “time-limited and revocable permit” would support “Europe’s ability to access reliable and affordable energy as they continue to transition away from Russian oil and gas”. Canada also announced it would expand sanctions against Russia’s energy sector to include industrial manufacturing. Kyiv urged the Canadian government not to return the part to Germany, but Germany, which is facing severe gas shortages, is being threatened with a further squeeze on Russian gas by Moscow if the turbine isn’t returned.
  
  Serhiy Bratchuk, a spokesperson for the Odesa regional military administration, said Russian forces were “purposefully” destroying crops in the Kherson region. He said fires occurred in the fields every day from shelling, and added: “Russian troops do not allow locals to put out fires, destroying granaries and equipment.”
  
  Ukraine president Volodymyr Zelenskiy has fired his ambassadors to Germany, India, the Czech Republic, Norway and Hungary, without giving further details as to why. Zelenskiy has urged his diplomats to drum up international support and high-end weapons to slow Russia’s advance. It was not immediately clear whether the envoys would be handed new jobs.
  
  Zelenskiy said on Saturday night the Russian army had attacked the cities of Mykolaiv, Kharkiv, Kryvy Rih, and communities of Zaporizhzhia region, covering a broad swathe of the country.
  
  Russia is moving forces across the country and assembling them near Ukraine for future offensive operations, according to the UK ministry of defence. The latest intelligence update said a large proportion of the new infantry units were “probably” deploying with MT-LB armoured vehicles taken from long-term storage.
  
  The governor of the Luhansk region said Russian forces were creating “hell” in shelling the eastern region of Donetsk. Serhiy Haidai said Russian forces fired eight artillery shells, three mortar shells and launched nine rocket strikes overnight.
  
  At least five people were killed on Saturday, and seven others injured, by renewed Russian shelling in Donetsk, Ukraine officials said. A missile attack in Druzkivka, northern Donetsk, tore apart a supermarket.
  
  US secretary of state Antony Blinken said his country’s “commitment to the people of Ukraine is resolute” while announcing more than $360m in additional aid.
  
  The United Nations said Ukraine’s armed forces bore a large, and perhaps equal, share of the blame for an assault at a nursing home in Luhansk, where dozens of elderly and disabled patients were trapped inside without water or electricity. At least 22 of the 71 patients survived, but the exact number killed remains unknown. A few days before the attack, Ukrainian soldiers took up positions inside the nursing home, making the building a target, the UN said.
  
  Kira Rudik, a Ukrainian MP with the centrist Golos party, said rockets struck central Kharkiv, injuring and hospitalising four civilians, including a child.
