Russian Foreign Minister Sergei Lavrov said on Monday that the fate of the nuclear non-proliferation regime is a source of grave concern amid escalating geopolitical tensions in the Middle East.

In a message to participants of the Moscow Nonproliferation Conference, Lavrov said the recent military actions by Israel and the United States (US) against Iran, including strikes targetting facilities under the safeguards of the International Atomic Energy Agency, had dealt a serious blow to the authority of the Treaty on the Non-Proliferation of Nuclear Weapons.
