China is providing intelligence to Russia to enable Moscow to better launch missile strikes inside Ukraine, a senior Ukrainian intelligence official has said. Ukrainian Foreign Intelligence Agency official Oleh Alexandrov told the state news agency Ukrinform that China was passing on satellite intelligence on targets, including those benefiting from foreign investment. “There is evidence of a high level of cooperation between Russia and China in conducting satellite reconnaissance of the territory of Ukraine in order to identify and further explore strategic objects for targeting,” he said. “As we have seen in recent months, these sites may belong to foreign investors.”

Ukraine’s air force said in the early morning on Sunday all of the country was under threat of fresh Russian missile attacks, following hours of air raid alerts and warnings of drone and missile attacks. Andriy Sadovyi, the mayor of Lviv, a western Ukrainian city about 70km (43 miles) from the border with Poland, said missiles were approaching the city after air defence systems were already engaged heavily in repelling a Russian drone attack.

Poland scrambled jets early on Sunday after the airstrikes on western Ukraine. “Polish and allied aircraft are operating in our airspace, while ground-based air defence and radar reconnaissance systems have been brought to the highest state of readiness,” Poland’s operational command said in a post on X. According to flight tracking service Flightradar24, early on Sunday, commercial flights were using routings typically used when Poland’s Lublin and Rzeszow airports near the border with Ukraine were closed.
