Ukraine President Sacks Security Chief, Cites Hundreds Of Treason Cases

Ukraine's President Volodymyr Zelenskiy sacked the head of the country's domestic security service and state prosecutor, citing hundreds of cases of alleged treason and collaboration with Russia, as Moscow appeared set to step up military operations.

Zelenskiy said more than 60 officials from the SBU security service and prosecutor's office were working against Ukraine in Russian-occupied territories, and 651 treason and collaboration cases had been opened against law enforcement officials.

The sackings on Sunday of Ivan Bakanov, head of the security service, and Prosecutor General Iryna Venediktova, who led efforts to prosecute Russian war crimes, and the sheer number of treason cases reveals the huge challenge of Russian infiltration as Kyiv battles Moscow in what it says is a fight for survival.

"Such an array of crimes against the foundations of thenational security of the state ... pose very serious questionsto the relevant leaders," Zelenskiy said. "Each of these questions will receive a proper answer.

In his nightly speech to the nation, Zelenskiy noted therecent arrest on suspicion of treason of the SBU's former headoverseeing the region of Crimea, the peninsula annexed by Russiain 2014 that Kyiv and the West still view as Ukrainian land.

Zelenskiy said he had fired the top security official at thestart of the invasion, a decision he said had now been shown tobe justified.

"Sufficient evidence has been collected to report thisperson on suspicion of treason. All his criminal activities aredocumented," he said.

3,000 CRUISE MISSILES

After failing to capture the capital Kyiv early in the invasion, Russian forces using a campaign of devastating bombing now control large swaths of Ukraine's south and east, where pro-Russian separatists already control territory.

Zelenskiy said Russia had used more than 3,000 cruise missiles to date and it was "impossible to count" the number of artillery and other strikes so far.

Dozens of relatives and local residents on Sunday attended the funeral of 4-year-old Liza Dmytrieva, one of 24 people killed in a Russian missile strike in the city of Vinnytsia last week.

Western deliveries of long-range arms are beginning to help Ukraine on the battlefield, with Kyiv citing a string of successful strikes carried out on 30 Russian logistics and ammunitions hubs, using several multiple launch rocket systems recently supplied by the West.

The strikes are causing havoc with Russian supply lines and have significantly reduced Russia's offensive capability, according to Ukraine's defence ministry.

Ukraine's southern Operational Command reported that in the Kherson region, it had destroyed two Russian Pantsir missile systems, three strategic communication systems, one radar station, two ammunition depots, and 11 armoured and military vehicles on Sunday.

The Russian military are also using radio-electronic warfare to suppress satellite communication channels, the Ukrainian General Staff said in a statement early on Monday.

RUSSIA INTENSIFIES OPERATIONS

Russia has ordered military units to intensify operations to prevent Ukrainian strikes on areas held by Russia, according to Ukraine which on the weekend reported shelling along the frontline in what it said was preparation for a fresh assault.

Ukraine's general staff said its forces had repelled Russian attacks in several towns in the Donetsk region.

"Fighting is currently ongoing near Hryhorivka near the administrative between Luhansk and Donetsk regions," it said.

Overnight at least 10 explosions were reported in the southern city of Mykolaiv, but there was no information on casualties, while two people were killed and 10 wounded in Avdiivka and Novy Donbas, said Ukraine's general staff, citing local officials.

Reuters could not immediately verify the reports.

The British defence ministry said on Sunday that Russia was reinforcing defences across areas it occupies in southern Ukraine after pressure from Ukrainian forces and pledges from Ukrainian leaders to drive Russia out.

Russian President Vladimir Putin launched his invasion on Feb. 24 calling it a "special military operation" to demilitarise its neighbour and rid it of dangerous nationalists.

Kyiv and the West say it was an imperialist land grab and attempt reconquer a country that broke free of Moscow's rule with the break-up of the Soviet Union in 1991.

The biggest conflict in Europe since World War Two has killed more than 5,000 people, forced more than 6 million to flee Ukraine and left 8 million internally displaced, says the United Nations.

Ukraine and the West say Russian forces are targeting civilians and been involved in war crimes, charges Moscow rejects.
