Zelenskyy has emphasized the importance of expanding production to counter Russia's invasion and strike deeper into Russian territory.

Russia launched 400 Shahed and decoy drones, as well as one ballistic missile, during the night, the Ukrainian air force said. The strikes targeted northeastern Kharkiv, which is Ukraine’s second-largest city, President Volodymyr Zelenskyy’s hometown of Kryvyi Rih in central Ukraine, Vinnytsia in the west and Odesa in the south.

Russia targeted Ukraine with more than 1,800 drones, 1,200 guided aerial bombs and 83 missiles of various types, President Zelenskyy said.

A Russian official says American Daniel Martindale has been rewarded with citizenship for spying on Ukraine, "by decree of our President Vladimir Putin."

Two Russian agents were killed by Ukrainian security forces Sunday following reports that the Russian operatives assassinated Ukrainian Colonel Ivan Voronych.

A new Ukrainian government approved Thursday will race to expand domestic arms production to meet half the country's weapons needs within six months as it tries to push back Russia's invasion, Ukrainian President Volodymyr Zelenskyy said.

Donald Trump has said Volodymyr Zelensky should not target Moscow after reportedly privately discussing strikes on the Russian capital with the Ukrainian leader."No, he shouldn't target Moscow," Mr Trump told reporters yesterday on the South Lawn of the White House when asked if Mr Zelensky should attack the Russian capital.
