A hard wind blows through the Ukrainian town of Marganets. It is coming across the Dnipro river, from the Zaporizhzhya nuclear power plant occupied by Russian troops.

Kyiv and Moscow accuse each other of shelling near the facility, with rockets striking a radioactive material storage area and the global atomic watchdog warning of a "grave" crisis.

Marganets is just 13 kilometers (8 miles) away. The leafy hilltop town remains in Ukrainian control, but between the thickets and across the shimmering river are foreboding glimpses of the Soviet-era station.
