headlines: Russia-Ukraine war: what we know on day 151 of the invasion 
articles: Russia has targeted Ukraine’s main port of Odesa – through which grain shipments would take place – with cruise missile strikes, barely 12 hours after Moscow signed a deal with Ukraine to allow monitored grain exports from Ukraine’s southern ports. “The enemy attacked the Odesa sea trade port with Kalibr cruise missiles,” Ukraine’s operational command south wrote on Telegram, raising doubts about the viability of the deal that was intended to release 20m tonnes of grain to ward off famine in large parts of the developing world.
  
  Ukrainian president Volodymyr Zelenskiy claimed the strikes on Odesa showed Moscow could not keep its promises. “This proves only one thing: no matter what Russia says and promises, it will find ways not to implement it,” he said during a meeting with US lawmakers, according to a statement from the presidency.
  
  The US secretary of state condemned the Russian attack against Odesa, accusing Russia of deepening the global food shortage. In a statement posted on Twitter, Antony Blinken said: “The United States strongly condemns Russia’s attack on the port of Odesa today. It undermines the effort to bring food to the hungry and the credibility of Russia’s commitments to the deal finalized yesterday to allow Ukrainian exports.”

  Hungary’s nationalist prime minister Viktor Orbán called for US-Russian peace talks to end the war in Ukraine, lashing out at the European Union’s strategy on the conflict. In a speech in Romania on Saturday, the 59-year-old rightwing leader also defended his vision of an “unmixed Hungarian race” as he criticised mixing with “non-Europeans”. Orban has condemned Russia’s invasion of Ukraine in February, but maintains an ambiguous position on the conflict.
