The escalation of attacks between Ukraine and Russia comes as U.S.-brokered peace talks between the countries have failed to come to fruition. High-level delegations from both Ukraine and Russia met in Istanbul, Turkey, on Monday for a second round of talks, but the proposed memorandums presented by each delegation have not moved forward in any meaningful way.

In a phone call between Russian President Vladimir Putin and President Donald Trump on Wednesday, the memorandums for a potential peace deal presented Monday were not discussed, Putin's aide Yuri Ushakov told reporters.

A U.S. official also said this week that there was evidence that Russia was preparing to retaliate against Ukraine for the drone strikes that targeted Russian military sites on Sunday.

The covert operation was described as one for the "history books" by Ukraine's President Volodymyr Zelenskyy.
