The fault lines between Ukraine and Russia run deep. Western and Ukrainian officials have raised alarms about a Russian military buildup near Ukraine, where Russian-backed separatists have been fighting Ukraine’s Western-allied forces since 2014. The Russian moves have brought concern over the possibility of the conflict escalating or even a Russian invasion of Ukraine — accusations that Moscow rejects.

The animosity was stoked Friday when Ukrainian President Volodymyr Zelensky asserted that a group of Russians and Ukrainians had plotted a coup attempt in Ukraine. A Kremlin spokesperson denied any Russian role in the alleged plot.
