Russia's Rosatom has raised fresh alarm over the safety of nuclear facilities, claiming Ukraine has launched more than 460 drone attacks and multiple artillery strikes near the Zaporizhzhia Nuclear Power Plant in recent months. Rosatom also announced it halted the return of staff to Iran's Bushehr nuclear plant after renewed attacks in the region. Meanwhile, IAEA Director-General Rafael Grossi warned that attacks on any nuclear power plant are "absolutely unacceptable," citing risks extending from Zaporizhzhia to Bushehr. Is the world entering a new phase of nuclear insecurity?
