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.

Belarusian military flexes its muscle near Ukrainian border
The Belarusian Defense Ministry announced “mobilization exercises” on Wednesday in the Gomel region bordering Ukraine.
The military drills, scheduled to last until July 1, will include special operations forces as well as freshly called up conscripts, Belarusian officials said on Telegram.
The Belarusian army has already been placing wooden dummies of tanks on the Ukrainian border to demonstrate their presence, Ukrainian Ministry of Defense spokesperson Alexander Motuzyanyk said on Wednesday.
Real weapons are arriving near the Ukrainian border, too, with a new batch of Russian missiles for the S-300 anti-aircraft missile system being brought to Belarus on Tuesday night, local monitoring groups reported. The delivery included at least 16 missiles, with the likely addition of one Pantsir missile defense system, the report said.
Still, Ukrainian officials maintain that “at this stage of the war,” there is no imminent threat “of the Belarusian army invading” Ukraine, Kyrylo Budanov, head of the Main Intelligence Directorate, said on Wednesday as cited by local media.

EU shifts to coal as Russia tightens gas tap
The European Union will temporarily shift back to coal to cope with slowing Russian gas flows, an EU official said on Wednesday, as a tight gas market and rocketing prices set off a race for alternative fuels.
"The unlawful invasion by Russia of Ukraine has resulted in an emergency situation in the EU," Elina Bardram, acting director for International Affairs and Climate Finance at the European Commission, told the Africa Energy Forum in Brussels, according to Reuters.
Bardram said the administration of Russian President Vladimir Putin was making “rogue moves” as Gazprom, the Russian state-controlled gas exporter, continued its policy of “lowering the flow [of gas] very suddenly.”

“We are taking some very important measures, but all of those measures are temporary," the EU official added, referring to the bloc's increasing coal use.
The International Energy Agency warned Russia could cut gas supplies to Europe completely this winter.
“Europe should be ready in case Russian gas is completely cut off,” IEA chief Fatih Birol told The Financial Times on Wednesday.
While Russia denies premeditated supply cuts, several European countries, including Germany and Italy, reported a dip in gas flow via pipelines from Russia over the past week.
