KYIV, Ukraine -- Leaders of Ukraine vowed Sunday not to cede any part of their nation's territory, even as Russia defended its virtual takeover of the disputed Crimean peninsula and signalled its willingness to act on the result of an upcoming secession vote there.
Pro-Russian forces tightened their grip on Crimea by laying siege to the last military airfield under Ukrainian control there and trying to seize control of other military installations in the strategically important region, a Ukrainian defence spokesman said. Residents proclaimed their loyalty to Ukraine or Russia in competing rallies, which produced some scuffles.
In Kyiv, the Ukrainian capital, thousands of people clutching blue-and-yellow national flags poured onto the streets to mark the bicentennial of the birth of Taras Shevchenko, their country's most famous poet and an ardent nationalist. Laying flowers at a statue of Shevchenko, acting Prime Minister Arseny Yatsenyuk declared he would not give up "one centimetre of Ukrainian land."
"Our parents and grandparents shed their blood for this land," he said, adding: "Let Russia and its president know this."
That would be Vladimir Putin, who for his part expressed his support for the March 16 public referendum planned by Crimea's regional assembly on splitting from Ukraine and joining Russia.
In telephone conversations Sunday with the leaders of Britain and Germany, Putin insisted the political events in Crimea were in line with international law, even though virtually no other nation has seconded that opinion and many, including the United States, have scoffed at it.
"The steps taken by the legitimate leadership of Crimea are based on the norms of international law and designed to cater to the legitimate interests of the peninsula's population," Putin said in a statement issued by the Kremlin. A majority of the region's residents are ethnic Russians or Russian-speakers.
The Kremlin's statement added there was a shared interest "in de-escalating the tension," which the U.S. and the European Union have demanded. Yet aggressive moves by pro-Russian forces -- who Putin denies are Russian soldiers, but who clearly use Russian uniforms and equipment -- continued across the peninsula over the weekend.
On Sunday, Russian troops backed by local militias laid siege to the airport at Novofyodorovka, the last military airstrip in Crimea in the hands of Ukrainian forces, said Alexei Mazepa, the Kyiv government's defence spokesman in the region. The Russians demanded Ukrainian personnel surrender their arms and leave the airport, which lies about 50 kilometres north of the regional capital of Simferopol.
Mazepa said in a telephone interview Russian forces had also surrounded an anti-aircraft unit in the resort city of Yevpatoria, ordering Ukrainian troops to surrender or face attack. Such ultimatums have repeatedly been issued to Ukrainian military installations in Crimea in recent days, though none has been carried out.
Mazepa also said Russian forces had crossed into mainland Ukraine in the Kherson region, capturing a hotel in the town of Chongar and "setting up minefields across the narrow strip of land that connects Ukraine with Crimea."
In a further attempt to consolidate Russia's hold on the peninsula, Vladimir Konstantinov, the Speaker of the regional parliament, said Ukrainian troops in Crimea could either defect or leave after next weekend's referendum, whose outcome Konstantinov and officials in Moscow speak of as practically a foregone conclusion.
"If you don't want to swear allegiance to the new authorities, we will do our best to help you leave the territory without any problems," Konstantinov said, the Interfax news agency reported.
