KIEV: Ukraine on Thursday placed its forces around Crimea on high alert as tensions soared after Moscow accused Kiev of attempting armed incursions into the disputed peninsula.
Russia’s FSB security service said on Wednesday it had thwarted “terrorist attacks” in Crimea this week by Ukrainian military intelligence and beaten back armed assaults, but Kiev fiercely denied the claims.
The allegations ratcheted up the heat in a feud sparked by Moscow’s 2014 seizure of the Black Sea peninsula from Ukraine and raised fears of possible wider conflict.
The UN Security Council was to discuss the growing tensions later Thursday at the request of Ukraine, a non-permanent council member.
Ukraine’s pro-Western President Petro Poroshenko met his top brass and ordered forces along the frontier with Crimea and across the conflict-wracked east onto “high-alert level”.
Russian President Vladimir Putin also held a meeting with security chiefs to discuss “additional measures for ensuring security for citizens and essential infrastructure in Crimea,” the Kremlin said in a statement.
“Scenarios were carefully considered for anti-terrorist security measures at the land border, in the waters and in the airspace of Crimea,” it said.
The FSB said one of its officers was killed in armed clashes while arresting “terrorists” on the night of August 6-7, while a Russian soldier died in a firefight with “sabotage-terrorist” groups sent by the Ukrainian military on August 8.
An irate Putin accused Kiev of “practising terror” and warned that the deaths of the two Russian officers would have consequences.
“We obviously will not let such things slide by,” Putin said. “This is a very dangerous game.”
Poroshenko hit back, saying Moscow’s claims were “senseless and cynical.”
“Fantasies are only another pretext for the next military threats toward Ukraine,” he said.
Two residents living on the Russian-controlled side of the Crimea-Ukraine frontier told AFP there had been an unexplained build-up of Russian military hardware in the area over the past few weeks.
Russia is holding nationwide legislative elections next month including in Crimea and the FSB said the alleged raids could be aimed at destabilising the situation ahead of the vote.
A senior Ukrainian security official told AFP that Moscow’s claims were a “crude Russian provocation” and that Kiev was “getting ready for anything,” including an invasion.
Russia says it has detained several Ukrainian and Russian citizens over the incident, including an alleged Ukrainian military intelligence officer named Yevgen Panov. Kiev has called Panov a “hostage”.
Moscow and Kiev have been locked in a bitter dispute since the Kremlin seized Crimea in March 2014 after Ukraine’s Russian-backed president Viktor Yanukovych was ousted.
The crisis sent ties between Moscow and the West plunging to their lowest point since the Cold War and led to tough economic sanctions by the EU and US against Russia.
The latest war of words represents the most serious increase in tensions in months as a separatist conflict in eastern Ukraine that Kiev and the West blame on Moscow drags on despite a stalled peace deal.
More than 9,500 people have been killed since the pro-Russian insurgency erupted in April 2014.
Putin said a mooted meeting with Poroshenko and mediators German Chancellor Angela Merkel and French President Francois Hollande at next month’s G20 summit in China was now “senseless”.
Independent Russian daily Vedomosti wrote in an op-ed entitled “A new old enemy” that Moscow has tended to ramp up tensions ahead of negotiations over Ukraine.
“The main political question now is what is the future of the Minsk process,” the paper wrote, referring to the peace deal hammered out in the Belarussian capital in February 2015.
“Will Russia bring an end to it or demand new concessions?”
