MOSCOW (REUTERS, AFP) - Russia's foreign ministry said on Thursday (Dec 1) Ukrainian missile tests near Crimea were a "dangerous precedent", Interfax news agency reported.
Ukraine's military said earlier on Thursday its two-day missile drills would avoid airspace over Crimea, sidestepping a possible confrontation with Russia which annexed the peninsula in 2014.
The drills near the Black Sea peninsula are a first for the former Soviet republic and it was not immediately clear what sparked them.
They come after Moscow last week arrested an alleged spy for the Ukrainian military in Crimea and accused Kiev of abducting two Russian servicemen from the region.
Kiev says Russia illegally annexed Crimea in March 2014 - a month after Ukraine's Russian-backed president was ousted in a pro-EU revolt.
It also accuses Moscow of backing a 31-month pro-Russian insurgency in Ukraine's industrial east in a conflict that has claimed nearly 10,000 lives.
A Ukrainian military spokesman told the 112.ua Ukraine news site that Kiev was not violating international laws.
"The launches have started. Everything is going according to plan. There has been no response from Russia but the Ukrainian military is ready for anything," Volodymyr Kryzhanovskiy was quoted as saying.
He said the war games included air defence units as well military drones and S-300 ground-to-air missile systems.
Kryzhanovskiy added that none of the missiles would land closer than 30km from Crimea.
Ukrainian media was full of speculation on Wednesday that Russia intended to shoot down the Ukrainian missiles once the tests began.
Ukrainian foreign ministry spokeswoman Mariana Betsa told the Ukrainska Pravda website that Kiev had received several "notes and letters from the Russian foreign and defence ministries" protesting the drills.
The messages stressed that the "tests supposedly violate the sovereignty of Russia and international law", Betsa was quoted as saying.
But Kremlin spokesman Dmitry Peskov told Thursday's online edition of the Vedomosti daily that Russia would indeed shoot down the missiles if it felt threatened.
Peskov said the tests could "create dangerous conditions for international flights crossing the territory of Russia and neighbouring regions".
Ukraine's national security council chief warned on Wednesday that such intimidation would not work.
"Threats to use weapons against Ukraine are an effort to turn the hybrid war that Russia has been waging against us for the past three years into an active war," Oleksandr Turchynov said.
