Ukraine urges NATO to deploy ships in dispute with Russia

KIEV, Ukraine -- The president of Ukraine is urging NATO to deploy warships to the Sea of Azov, a proposal sharply criticized by Russia as a provocation potentially worsening tensions between the two countries following a weekend confrontation in the waters off the Crimean Peninsula.

U.S. President Donald Trump said Thursday he was canceling a planned meeting with Russian President Vladimir Putin at the G-20 summit in Argentina because Moscow has not released the Ukrainian vessels and sailors it seized.

In an interview published earlier Thursday with the German daily Bild, Ukrainian President Petro Poroshenko laid out his hope NATO would "relocate naval ships to the Sea of Azov in order to assist Ukraine and provide security" against Putin's expansionist ambitions.

The Russian coast guard fired on and seized three Ukrainian vessels and their crews Sunday. Russia alleged the Ukrainian vessels had failed to obtain permission to pass from the Black Sea into the Sea of Azov through the Kerch Strait. Ukraine insisted its vessels were operating in line with international maritime rules in the strait, which separates Russia's mainland and the Crimean Peninsula it annexed from Ukraine in 2014.

While condemning the Russian action, NATO is not expected to send ships to the area; a deployment could trigger a confrontation with Russia. A 2003 treaty between Russia and Ukraine stipulates permission from both countries is required for warships from anywhere else to enter the internal sea.

NATO spokeswoman Oana Lungescu said the alliance already has a strong presence in the region, and NATO ships routinely patrol and conduct exercises in the Black Sea, especially those from Bulgaria, Romania and Turkey, which border the sea.

German Chancellor Angela Merkel said early Thursday she plans to press Putin at the upcoming G-20 summit in Argentina to urge the release of the Ukrainian ships and crews and to de-escalate the situation.

"We can only resolve this in talks with one another because there is no military solution to all of these conflicts," she said.

The Ukrainian government said Russia has blocked commercial traffic to and from Ukrainian ports on the Sea of Azov, which Russia quickly denied.

"Putin wants nothing less but to occupy the sea," Poroshenko said. "The only language he understands is the unity of the Western world."

Putin on Wednesday criticized the West for what he described as connivance with Ukraine's "provocation."

"The authorities in Kiev are successfully selling anti-Russian sentiments as they have nothing else left to sell," he said. "They can get away with whatever they do. If they want to eat babies for breakfast today, they will likely get served, too."

In response to Sunday's events, Ukraine has imposed martial law in parts of the country. Putin accused Poroshenko of provoking the naval incident in a bid to impose martial law to shore up his sagging popularity and sideline competitors ahead of a presidential election in March.

Putin said Poroshenko's request for NATO warships is "clearly aimed at provoking further tensions," adding it was driven by "electoral and domestic policy motives."

Poroshenko said martial law wouldn't restrict travel, cash withdrawals or currency purchases by Ukrainians, but Russians will face what he described as "restrictions."

Later Thursday, Ukrainian border guards announced all non-Ukrainians will be barred from crossing into the Russia-occupied Crimea by land after martial law went into effect.

While it is still possible to fly into Crimea from Russia or drive in on the new bridge across the Kerch Strait from southern Russia, Ukraine considers that a violation of its borders. Thus, the ban means that non-Ukrainians will either risk criminal liability in Ukraine or refrain from traveling to Crimea until the end of the year.

Ukraine's Ministry of Infrastructure said Russia has blocked 35 merchant ships from leaving or entering the Sea of Azov since Wednesday.

The ministry said 18 ships have been stuck in the Black Sea, waiting to pass through the Kerch Strait into the Sea of Azov. Another 17 vessels were unable to leave the Ukrainian ports of Mariupol and Berdyansk on the Sea of Azov, it said.

Peskov insisted Russia hasn't imposed any restrictions on the ships' passage, adding a possible logjam could be linked to poor weather.

Ukraine's intelligence agency, the SBU, said a Russian fighter jet and a helicopter fired rockets Sunday at the three Ukrainian vessels before they were captured -- the first time an airstrike was reported.

"It's a miracle the Ukrainian seamen have survived," SBU deputy chief Oleh Frolov told reporters.

There has been growing hostility between Ukraine and Russia since Moscow's annexation of the Crimean Peninsula from Ukraine in 2014. Russia has also supported separatists in Ukraine's east with clandestine dispatches of troops and weapons. Fighting there has killed at least 10,000 people since 2014 but eased somewhat after a 2015 truce.
