"The situation, particularly the deaths of many dozens of Palestinians, cannot but provoke the deepest concern," Kremlin spokesman Dmitry Peskov told journalists.
"Moscow expressed concern from the start over the actions of the US that could lead to provoking tensions in the Middle East," Peskov said.
"Unfortunately, that's how it worked out."
Russian President Vladimir Putin warned in December that the US decision to move its embassy from Tel Aviv to Jerusalem "does not help regulate the situation in the Middle East but instead destabilises the already-complicated atmosphere."
Jerusalem is one of the most thorny issues of the Israeli-Palestinian conflict, with both sides claiming it as their capital.
Most of the international community does not formally recognise Jerusalem as Israel's capital, and almost all embassies are located in Tel Aviv.
