Russia attacked Ukraine's energy system and some cities with cruise and ballistic missiles plus drones, Ukraine's President Volodymyr Zelenskiy said.

Ukraine's air force says it detected 184 missiles and drones, causing damage to energy infrastructure across the country.

Thirty eight people were killed and dozens survived a plane crash in Kazakhstan while traveling to southern Russia, according to local officials, as speculation swirls online that Russia could somehow have been responsible for the crash.

An Azerbaijani airliner has crashed in Kazakhstan after being diverted, killing 38 of 67 people on board. Some things to know about the crash and the speculation about a possible cause: How did the plane crash?

A passenger plane flying from Azerbaijan to Russia with 67 people on board crashed in Kazakhstan Wednesday, authorities said.

The flight was en route from the Azerbaijani capital of Baku to Grozny, in Russia’s south, when it diverted and attempted an emergency landing in Kazakhstan.

Officials in Russia and Kazakhstan are urging people to wait for an investigation into the deadly Azerbaijan Airlines plane crash before assigning blame.

"No one claims that it was done on purpose," an Azerbaijan official told Reuters. They added their government "expects the Russian side to confess."
