U.S. President Donald Trump said Ukraine must compensate Russia for destroyed aircraft, adding: "They were just sitting there, not bothering anyone. If the Ukrainians had shot them down during a combat mission, that would be a different matter. But they were just sitting there. It's like hitting someone who's already down."

The Security Service of Ukraine said that the operation, which it codenamed “Web”, had destroyed 34% of Russia's fleet of air missile carriers with damages estimated at $7 billion.

Russian and Ukrainian officials are due to hold peace talks in Istanbul with no sign they are any closer to an agreement.
