North Korea has denied its soldiers' alleged border breaches and threatened unspecified responses.

President Emmanuel Macron and Ukrainian counterpart Volodymyr Zelensky Monday signed a letter of intent for Kyiv to acquire up to 100 Rafale fighter jets and other air defense hardware from French companies, the French presidency said.
