Why would Russia or Ukraine risk attacking a nuclear plant?

The area around a nuclear facility in Ukraine’s Zaporizhzhia has come under heavy artillery strikes.

Ukraine and Russia are blaming each other for strikes around Zaporizhzhia nuclear plant in recent weeks, but why would anyone want to take such a risk?

Retired Colonel Hamish De Bretton-Gordon, a chemical weapons expert, says the risk of disaster "couldn't be higher" but that the plant is much newer than the infamous Chernobyl plant, with better-protected reactors.

However, the risk to the global environment remains a key question, as Russian claims to have placed explosives inside a reactor.

"If they blew up that, that could create a chain reaction that would put massive amounts of contamination all across Europe," he added, concerned such an incident would trigger NATO's Article V and demand a united military response.
