Russian President Vladimir Putin's "special military operation" into neighboring Ukraine began on Feb. 24, with Russian forces invading from Belarus, to the north, and Russia, to the east. Ukrainian troops have offered "stiff resistance," according to U.S. officials.
The Russian military has since launched a full-scale ground offensive in eastern Ukraine's disputed Donbas region, capturing the strategic port city of Mariupol and securing a coastal corridor to the Moscow-annexed Crimean Peninsula.

Russia refuses to create demilitarized zone around Zaporizhzhia nuclear power plant
The international calls and proposals for Russia to create a demilitarized zone around the Zaporizhzhia nuclear power plant in southeastern Ukraine are "unacceptable," according to Ivan Nechayev, deputy director of the Russian Foreign Ministry's Information and Press Department.
"Their implementation will make the plant even more vulnerable," Nechayev said at a press briefing on Thursday.
Moscow is expecting experts from the International Atomic Energy Agency, the nuclear watchdog of the United Nations, to visit the Zaporizhzhia plant "in the near future," according to Nechayev.

The secretary-generals of the U.N. and the IAEA have called for the establishment of a demilitarized zone around the Russian-occupied Zaporizhzhia plant, which is the largest nuclear power plant in Europe.
One of the rockets struck a large apartment block on Wednesday night, killing at least nine people and injuring another 16, according to Ukrainian authorities.

"It went through all four floors and hit the ground and almost blew up everything," the firefighter, Roman Kachanov, told ABC News during an interview on Thursday. "All the buildings around were without windows."
"There was a dormitory, and the building was almost completely ruined," he added. "There was a playground that was smashed like a big titan blew it up."

Kachanov is among the rescue workers searching for survivors amid the smoldering rubble.
"I’ve seen three bodies on the floor covered by objects," he said. "We tried to extract them and while we tried, the other wall started to fall and we had to run away as fast as we can."

Kachanov said another missile hit the city before dawn Thursday, not far from where he and his team were working. He said the blast "was very loud" and "sounded close."
"Everyone had to lay down," he recalled. "The team had to split -- fire truck had to leave to go to that other fire."

Enerhodar Mayor Dmytro Orlov urged residents to stay inside. He said Russian forces seized another government facility in Enerhodar, a lab where 30 of the employees are refusing to cooperate with the Russian-appointed administration.
Meanwhile, Russia's semi-official Interfax reported that Ukrainian forces opened fire in Enerhodar.
Ukraine's state nuclear regulator Energoatom said the plant remained occupied and controlled by Russian forces on Monday. The Ukrainian staff continues to work and make every effort to ensure nuclear and radiation safety, but Energoatom warned that periodic shelling by Russian troops with multiple rocket launchers since last week caused a serious risk to the safe operation of the plant.
In his daily address, Ukrainian President Volodymyr Zelenskyy said Russian troops must immediately withdraw from the plant. If a catastrophe occurs, Zelenskyy warned it could affect neighboring countries.
