The Ukrainian government's recent shake-up drew attention to corruption allegations implicating senior officials. Here's a short history of the country's efforts to combat graft.

A string of resignations, dismissals and reassignments shook Ukraine's government early this week, as Ukrainian President Volodymyr Zelenskyy and other leaders of the government confirmed the shakeup.

The attack was one of the deadliest strikes on the Kremlin's forces since the start of the war 10 months ago. Ukraine claimed to have killed hundreds of Russian conscripts, but details are murky.

Ukraine's government issued 15,000 air raid warnings in 2022, and it doesn't look like Russia is planning to let up this year.

At least one person was killed and several injured in Kyiv after Russia launched a new wave of missiles against the capital and other cities across Ukraine.

Russian forces fired its largest air barrage into Ukraine in nearly two weeks Thursday as Ukrainian air defenses repelled several drones and missiles throughout the attack.

That would be a year since Russia launched its full-scale invasion against Ukraine. The proposal comes a day after Russia's president accused Ukraine of being unwilling to negotiate an end to the war.

Regional military administrators across the country say Russia launched more than 70 missiles targeting at least 10 of Ukraine's 24 regions.

International atomic experts have warned of a potential nuclear disaster with Ukraine's Zaporizhzhia plant in the middle of a war zone, bringing back terrifying memories of Chernobyl.

Over 1.4 million households have lost electricity after repeated Russian air raids, the president's office says. Ukraine's power utility says the extent of the damage eclipses earlier attacks.

The move signals Russia's growing frustration over Ukrainian advances in areas the Kremlin claimed to annex. It came hours after Kremlin-appointed officials ordered civilians to evacuate Kherson.

Explosions rang out across Kyiv early Monday, a week after nationwide strikes rocked the city for the first time since June.

Theories abound about who is responsible for the attack and how they did it. On Wednesday, Russia arrested eight men alleged to have set off a truck bomb. Ukraine says Russia planned the attack.

Security agents arrested five Russians, two Ukrainians and an Armenian as suspects in the explosion, which disabled a critical link between Russia and the Ukrainian peninsula it annexed in 2014.

Workers and those living around the remains of the Chernobyl nuclear plant recall their experiences as they see Russia's invasion endanger another power plant.

The attacks came only hours after Russia blamed Ukraine for a weekend explosion that partially damaged a strategic bridge that connects Russian-occupied Crimea to mainland Russia.

The 12-mile bridge has served as a key auto and rail supply line from Russia into Crimea. A Ukrainian official said the incident was just "the beginning," but stopped short of taking credit.

While the Ukrainian organization that won is celebrating, many Ukrainians are upset they need to share the award with countries that have been aggressive against them.

The winners of this year's Nobel Peace Prize are recognized, the Nobel Committee said, for years of protecting the fundamental rights of citizens in Russia, Ukraine and Belarus.
