The head of the International Atomic Energy Agency (IAEA) says that part of the mission to the Russia-held Zaporizhzhia nuclear plant in southern Ukraine will stay at the facility "until Sunday or Monday". "There is a group that is going to be there (at the plant) until Sunday or Monday, continuing with the assessment," Rafael Grossi, who is leading an inspection of the frequently shelled plant, told reporters after he returned with part of his 14-strong team to the Ukrainian-controlled area. He did not specify how many people will be staying at the facility. SOUNDBITE
