The Russian Defense Ministry on Monday said it would "return" more than 10 warplanes to Crimea, according to Russian news agency Interfax.
The ministry said fighter jets, including Sukhoi Su-27 and Su-30's, will be sent to the annexed Ukrainian territory as part of a "permanent deployment." They are expected to arrive by Saturday.
The announcement comes after Russian Foreign Minister Sergey Lavrov claimed in an interview that Ukraine was preparing an "armed provocation with Russia on the border with Crimea during the last ten days of December."
Neo-Nazi characteristics'
In comments carried by the state-run TASS news agency, Lavrov said Moscow would not allow the Ukrainian government to act on those plans, saying "they will regret it." But he also said that Russia "will not wage war against Ukraine."
"We are not fighting the Ukrainian regime," Lavrov said. "It is Ukrainian citizens living in Donbasswho are fighting against the Ukrainian regime, which has full Nazi and neo-Nazi characteristics."
Last month, Russian warships captured three Ukrainian naval vessels as they crossed through the strategic Kerch Strait, detaining 24 sailors on board. Russian authorities accused the Ukrainian vessels of military provocations.
From annexation to church split
The incident has further strained relations between Ukraine and Russia, which have been in tatters since a revolution in Ukraine was followed by Moscow launching a military intervention in Crimea and subsequently annexing the Ukrainian territory under an internationally-condemned referendum four years ago.
Russia's actions were largely seen as a response to the ouster of Kremlin ally and former Ukrainian president, Viktor Yanukovych, as a result of anti-government protests. Those events in early 2014 inflamed pro-Russia sentiment in eastern Ukraine, triggering an armed insurgency against the Ukrainian state.
Tensions between Moscow and Kyiv have also impacted relations within the Russian and Ukrainian orthodox churches. On Saturday, a council of Orthodox bishops in Ukraine formally created a new Ukrainian church, effectively severing ties with its Russian steward.
