Ukrainian Defense Minister Oleksiy Reznikov denied Ukraine was involved in the bombing of the Nord Stream pipeline, which carries natural gas from Russia to Germany. While the pipeline was not active at the time of the bombing last September, it was filled with fuel.

The denial comes after The New York Times reported that intelligence reviewed by U.S. officials suggests a pro-Ukrainian group carried out the Nord Stream bombings last year.

After the story broke, German Defense Minister Boris Pistorius warned against “jumping to conclusions” about who carried out the explosion, suggesting it could have been a “false flag” operation to blame Ukraine.

German authorities were reportedly able to identify the boat used for the sabotage operation, saying a group of five men and one woman using forged passports rented a yacht from a Poland-based company owned by Ukrainian citizens. The nationalities of the perpetrators are unclear, according to a separate report by Germany’s ARD broadcaster and Zeit newspaper.

“We have to make a clear distinction whether it was a Ukrainian group, whether it may have happened at Ukrainian orders, or a pro-Ukrainian group [acting] without knowledge of the government. But I am warning against jumping to conclusions,” Pistorius said on the sidelines of a summit in Stockholm.

A Russian diplomat said Russia has no faith in the U.S.‘s “impartiality” in the conclusions made from intelligence.

Chinese President Xi Jinping hadn't even left Moscow when the drones started exploding. It came a matter of hours after Xi and Russian President Vladimir Putin proclaimed they were the ones who wanted to make "peace" in Ukraine.

Ukrainian officials say 21 lethal attack drones were launched overnight and into this morning by Russia, with 16 shot down by the Ukrainians.

An apartment block was hit in a town southeast of Kyiv, killing at least four people and injuring others, officials said. Russian officials claim Ukrainian soldiers were based there. The Ukrainians are calling it a "civilian" building.

Russian missiles later hit an apartment block in the heart of the southern Ukrainian city of Zaporizhzhia.

And in an apparent repost to the geopolitical theatrics in Moscow, Ukrainian President Volodymyr Zelenskyy visited his troops on Wednesday in the eastern Donbas, not far from the embattled city of Bakhmut, according to his officials.

Bakhmut has become a potent symbol of Ukrainian resistance and sacrifice and despite being surrounded on three sides Ukrainian forces inside the city are, after months of fighting there, still holding on.

Zelenskyy's office released video of him addressing troops and also visiting injured soldiers in a military medical facility in the region. He told troops their "destiny was difficult but important" because they were fighting to save the motherland.
