The situation at the Zaporizhzhia nuclear plant has not improved, according to director general of the International Atomic Energy Agency Rafael Grossi.

The plant has been occupied by Russian forces since March of last year and is now run by the Russian atomic agency, ROSATOM.

Grossi said military activity and the number of troops in the area were increasing, without specifying whether he meant both Russian and Ukrainian forces. Ukrainian troops are stationed several miles across the reservoir from the plant.

He said original plans to create a demilitarized zone around the plant had “evolved” toward greater protection of the plant itself and added there should not be heavy military equipment at the plant. Ukraine has accused the Russians of basing rocket systems at the plant, which Moscow has denied.

Grossi said he was trying to formulate “realistic, viable proposals” that would be acceptable to both sides.
