The United Nations Security Council (UNSC) held a meeting on the Russia-Ukraine conflict on Wednesday, six months after it began on February 24.

The meeting mainly focused on the maintenance of peace and security in Ukraine, said the UNSC.

At the "sad and tragic milestone," UN Secretary-General Antonio Guterres said that warning lights are flashing at the Zaporizhzhia nuclear power plant in southern Ukraine, and the security of the plant must be stabilized.

The food crisis also topped the meeting's agenda.

"The acceleration of already high food, fertilizer and fuel prices has triggered a global crisis that could drive millions more into extreme poverty, magnifying hunger and malnutrition, while threatening to raise the global humanitarian caseload to new highs and erase hard-won development gains," Guterres said.
