The second round of Ukraine-Russia peace talks started in Abu Dhabi, with both sides doubtful about quick progress. Ukrainian President Volodymyr Zelenskyy said Moscow launched a "massive" and "deliberate" attack overnight, firing a record 71 ballistic missiles and 450 drones to destroy energy infrastructure. Kyiv faced freezing temperatures near -20C, and over 1,000 homes lost heating. Injuries were reported across Kyiv and other cities like Zaporizhzhia, where a drone strike killed two teenagers and wounded 11. US President Donald Trump claimed these strikes did not break Russia's week-long pledge to avoid hitting energy sites. However, NATO chief Mark Rutte said the attacks "did not signal seriousness about peace." Ukrainian, US, and European officials agreed that further Russian violations of any ceasefire would trigger a coordinated military response. Meanwhile, the New START nuclear treaty between the US and Russia is set to expire on Thursday, removing key limits on their nuclear arsenals. Despite war fatigue and cold hardship, many Ukrainians resist any peace deal giving up the Donbas region to Russia, fearing it would only encourage further aggression. Polls in Russia show growing support for talks but no readiness to make territorial concessions. The talks continue under tough conditions and tense diplomacy.
