KYIV, March 15 - Russia and the United States ratcheted up their confrontational rhetoric Wednesday over a U.S. surveillance drone that encountered Russian warplanes and crashed near Ukraine’s Crimean Peninsula, which the Kremlin has illegally annexed.

At the same time, the two countries’ defense chiefs opened a dialogue about the incident, The Associated Press reported.

U.S. officials said the incident showed Russia’s aggressive and risky behavior and pledged to continue their surveillance.

The Kremlin said the flight proved again that Washington is directly involved in the fighting in Ukraine and added that Moscow would try to recover the drone’s wreckage from the Black Sea.

Russia has long voiced concern about U.S. surveillance flights near its borders, but Tuesday’s incident signaled Moscow’s increasing readiness to raise the ante as tensions soar between the two nuclear powers. It reflected the Kremlin’s appetite for brinkmanship that could further destabilize the situation and lead to more direct confrontations.

U.S. Defense Secretary Lloyd Austin, who said the incident was part of a “pattern of aggressive, risky and unsafe actions by Russian pilots in international airspace,” spoke to his Russian counterpart, Sergei Shoigu, on Wednesday for the first time in five months.

“It’s important that great powers be models of transparency and communication, and the United States will continue to fly and to operate wherever international law allows,” Austin told reporters in Washington.

The Russian Defense Ministry said in its report of the call with Austin that Shoigu noted the U.S. had provoked the incident by ignoring flight restrictions the Kremlin had imposed due to its military operation in Ukraine and also blamed “the intensification of intelligence activities against the interests of the Russian Federation.”

Nikolai Patrushev, the secretary of Russia’s Security Council, said in televised remarks the drone incident was “another confirmation” of direct U.S. involvement in the Ukraine conflict. The Kremlin has repeatedly said the United States and other NATO members have become direct war participants by supplying weapons and intelligence to the Kyiv government and pressuring it not to negotiate peace.

U.S. officials said Russia dispatched ships to try to recover the wreckage, which Milley said were likely submerged 4,000 to 5,000 feet (1,200 to 1,500 meters) deep.

The U.S. has no vessels in the Black Sea because Turkey closed the Bosphorus Strait to warships in 2022, except for those returning to home port.

U.S. National Security Council spokesperson John Kirby said the drone was in international airspace when the Russian warplane struck its propeller. U.S. officials accused Russia of trying to intercept the unmanned aircraft, although its presence over the Black Sea — a strategic military and economic area for both Russia and Ukraine — was not uncommon.
