“Ultimately, it is up to our Ukrainian partners to decide how and where it is better to use these weapons and supplies to protect their territory,” RIA Novosti quoted him as saying.
According to a State Department spokesman, Washington does not make decisions about Ukrainian targets.
He also stressed that the United States does not encourage Kyiv to attack Russia and does not assist it, but does not recognize Crimea as Russian territory.
On December 5, The Wall Street Journal reported that the United States had secretly modified the HIMARS MLRS given to the Ukrainian army so that they could not be used to launch long-range missiles against Russia.
Earlier, Ukrainian Foreign Minister Dmitry Kuleba said that the United States does not prohibit Kyiv from using American weapons against Crimea.
The Kremlin noted that Crimea is an integral part of Russia and claims to Russian territory will receive a proper response.
Crimea became a Russian region after a referendum held there in March 2014: the majority of residents voted for reunification with Russia.
