Tensions rise between U.S. and Russia after drone collision

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