You're reading: Reuters: Putin aide warns U.S. on Ukraine, says Russia could act

A senior Kremlin aide accused the United States on Feb. 6 of arming Ukrainian "rebels" and, urging the Kiev government to put down what it called an attempted coup, warned it could intervene to maintain the security of its ex-Soviet neighbor.

Sergei Glazyev, an adviser to President Vladimir
Putin with responsibility for relations with Ukraine, told a newspaper
that U.S. “interference” breached the 1994 treaty under which Washington
and Moscow jointly guaranteed Ukraine’s security and sovereignty after
Kiev gave up its Soviet-era nuclear arsenal.
