Phillip Schofield has shared his fears of a nuclear World War following Russia's war crime after an airstrike at a children's hospital in Mariupol.
The This Morning star, 59, spoke solemnly as he discussed the tragic airstrike which has shocked the world.
The harrowing attack has so far, killed three people, including a six-year-old child.
It has also wounded at least 17 people, including women who were waiting to give birth, doctors, and children who were buried under the rubble.
Discussing the after-effects of the devastating airstrikes, Phillip considered the possibility of a nuclear World War if NATO condemn Putin's target on the children's hospital.
"We talk about war crimes and we talk about NATO - it would appear an absolute red line that NATO would cross that border because there is some exchange of fire," Phillip shared.
"But we could be in a World War - we could be in a nuclear World War. Everyone is going to have to tread very carefully as there is potential talk of biological weapons and chemical weapons which are heavier than air and they seep down into the cellars.
"It's harrowing."
Following Phil's confession, This Morning viewers flocked to Twitter to share their thoughts.
"This is terrifying. Even watching This Morning I'm not safe from feeling scared," one viewer wrote.
"There's so much sadness in the world right now. I can't help but feel Phillip is right, it all feels so ominous," another echoed.
"OMG turned on This Morning and I'm traumatised. Not watching TV for the rest of the day," someone else shared.
Meanwhile, a fourth tweeted: "We should all count ourselves so lucky that we live in the UK. What's going on in the world is disgusting right now."
It comes after Ukrainian President Volodymyr Zelenskyy accused Russia of carrying out genocide after officials reported Russian aircraft had bombed the children's hospital on Wednesday.
"A children's hospital. A maternity hospital. How did they threaten the Russian Federation?" Mr Zelenskyy asked in his nightly video address.
"What kind of country is this, the Russian Federation, which is afraid of hospitals, afraid of maternity hospitals, and destroys them?"
"There are few things more depraved than targeting the vulnerable and defenceless," Prime Minister Boris Johnson tweeted. He said Russian President Vladimir Putin will be held "to account for his terrible crimes."
Bombs also fell on two other hospitals in another city west of the capital.
The World Health Organisation (WHO) has said it has confirmed 10 people died and 16 injured in attacks on health facilities and ambulances since the fighting began - it was unclear if this figure included the attack on the maternity hospital.
