U.S. military commentators praised Ukraine's "remarkable" Trojan Horse-like use of wooden sheds as it bombed as deep into Russia as Siberia.

Ukraine reviews Russia's ceasefire terms after failed talks. Zelenskyy emphasizes no rewards for Putin and highlights NATO's importance in curbing Russian aggression.

Officials from Russia and Ukraine in Istanbul on Monday failed to reach a ceasefire but agreed to exchange more prisoners.

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

The second round of talks was even shorter than the first and didn’t address any substantive issues to ending the three-year conflict.

With 41 military aircraft impacted, the Ukrainian drone attack was described by some commentators as Russia's "Pearl Harbor."

Russian and Ukrainian delegates are meeting in Istanbul on Monday for their second set of direct peace talks, a day after Kyiv launched a shock drone attack on Russia’s nuclear-capable bombers.

Russia told Ukraine at peace talks on Monday that it would only agree to end the war if Kyiv gives up big new chunks of territory and accepts limits on the size of its army, according to a memorandum reported by Russian media.

Ukraine suspects Russia is not really interested in pausing the conflict and ending the war, and the head of the country’s delegation, Defence Minister Rustem Umerov, said the key points could only be resolved at face-to-face talks between President Zelensky and President Putin.
