KYIV, Sept 26 - A young man shot a Russian military officer at close range at an enlistment office Monday, an unusually bold attack reflecting resistance to Russian President Vladimir Putin’s efforts to mobilize hundreds of thousands of more men to wage war on Ukraine.

The shooting comes after scattered arson attacks on enlistment offices and protests in Russian cities against the military call-up that have resulted in at least 2,000 arrests, The Associated Press reported. Russia is seeking to bolster its military as its Ukraine offensive has bogged down.

In the attack in the Siberian city of Ust-Ilimsk, 25-year-old resident Ruslan Zinin walked into the enlistment office saying “no one will go to fight” and “we will all go home now,” according to local media.

Zinin was arrested and officials vowed tough punishment. Authorities said the military commandant was in intensive care.

Protests also flared up in Dagestan, one of Russia’s poorer regions in the North Caucasus. Local media reported that “several hundred” demonstrators took to the streets Tuesday in its capital, Makhachkala. Videos circulated online showing dozens of protesters tussling with the police sent to disperse them.

Demonstrations also continued in another of Russia’s North Caucasus republics, Kabardino-Balkaria, where videos on social media showed a local official attempting to address a crowd of women.

Elsewhere, the British government on Monday slapped sanctions on 92 businesses and individuals it says are involved with organizing the referendums in occupied Ukraine. U.K. Foreign Secretary James Cleverly called the votes on joining Russia “sham referendums held at the barrel of a gun.” He said they “follow a clear pattern of violence, intimidation, torture and forced deportations.”

The White House Press Secretary Karine Jean-Pierre likewise said Monday the U.S. “will never recognize” the four regions as part of Russia, and threatened Moscow with “swift and severe” economic costs.

Putin and his Belarusian counterpart Alexander Lukashenko, meanwhile, held an unannounced meeting Monday in the southern Russian city of Sochi and claimed they were ready to cooperate with the West — “if they treat us with respect,” Putin said.

The Kremlin last week announced a partial mobilization — its first since World War II — to add at least 300,000 troops to its forces in Ukraine. The move, a sharp shift from Putin’s previous efforts to portray the war as a limited military operation, proved unpopular at home.

Thousands of Russian men of fighting age have flocked to airports and Russia’s land border crossings to avoid being called up.

President Volodymyr Zelensky on Monday decried the Russian mobilization as nothing more than “an attempt to provide commanders on the ground with a constant stream of cannon fodder.”

In his nightly televised address, Zelensky referenced ongoing Russian attempts to punch through Ukrainian defense lines in the eastern industrial heartland of Donbas, a key target of Moscow’s military campaign.

“Despite the obvious senselessness of the war for Russia and the occupiers’ loss of initiative, the Russian military command still drives (troops) to their deaths,” Zelensky said in his nightly televised address. (ap/ez)
