Why would Russia or Ukraine risk attacking a nuclear plant?

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.
