Putin will avenge destruction of Russian warplanes by Ukraine warns Donald Trump | BBC News

Vladimir Putin said he would respond very strongly to Ukraine's drone attack on Russian airbases, while U.S. President Donald Trump warned that the call with Putin would not lead to immediate peace. Trump noted that the U.S. was not warned of the attack and that Russia had rejected an unconditional ceasefire. The leaders' conversation followed a second round of peace talks in Istanbul that ended without a breakthrough, and came after Russia stepped up drone and missile attacks on Ukrainian cities.
