The Kremlin said Friday it was concerned by Israel’s overnight strikes on Iran, condemning what it called a “dramatic escalation” of tensions between the two countries.

Top spokesman Dmitry Peskov said President Vladimir Putin was receiving “real-time updates” on the situation after the Israel Defense Forces carried out large-scale attacks on “dozens” of sites across Iran, including its nuclear program, and reportedly killed several top military officials.

Russia’s Foreign Ministry later accused Israel of violating the UN Charter and international law, describing the overnight assault as “unprovoked military strikes against a sovereign UN member state, its citizens, sleeping peaceful cities and nuclear energy infrastructure.”

“The international community cannot afford to turn a blind eye to such acts of aggression, which threaten peace and undermine both regional and global security,” the ministry said in a statement.

“What makes the situation especially cynical is that these Israeli attacks took place in the midst of an IAEA Board of Governors session and just before another round of indirect talks between Iran and the United States,” it added.
