Delegations from Russia and Ukraine are in Turkey for their second round of direct peace talks in just over two weeks.

Ukrainian President Volodymyr Zelenskyy said he was sending a Ukrainian delegation to Istanbul for another face-to-face with Russian representatives.

Ukraine’s security service released footage Wednesday of its attack on Russian war planes at multiple airbases across the country. In the span of a few hours on Sunday, nearly a third of Moscow’s strategic bomber fleet was destroyed or damaged with cheaply made drones sneaked into Russian territory, according to Ukrainian officials.
