The International Atomic Energy Agency (IAEA) head, Rafael Grossi, has said the agency would consider establishing a continued presence at Ukraine’s Zaporizhzhia nuclear power plant.

“There has been increased military activity including this morning, until very recently, a few minutes ago … but weighing the pros and cons and having come so far, we are not stopping,” Reuters reports he told journalists before setting out for the nuclear power plant.

Today, at about 6am Moscow time, Ukrainian troops landed on the coast of the Kakhovka Reservoir, 3 km northeast of the ZNPP plant in two sabotage groups of up to 60 people in seven boats and attempted to seize the power plant. Measures have been taken to destroy the enemy, including with the use of army aviation.

In addition, from 8am Moscow time, the armed forces of Ukraine have been shelling the meeting point of the IAEA mission in the area of ​​​​the settlement of Vasylivka and the ZNPP. Four shells exploded at a distance of 400m from the first power unit.
