BBC radio host Ritula Shah was forced intervene after a furious row erupted between Labour MP Chris Williamson and Tory MP Chris Philp during a heated live interview.
The heated exchange began during a debate about whether Britain should take military action following the suspected chemical weapon attack in Syria.
Dozens of people, including children, died in the incident in the war-torn country.
US President Donald Trump, backed by Britain and France, has proposed military action against the Syrian regime in response to the suspected chemical attack.
Labour MP Chris Williamson was asked what his reaction would be if the Government decides to take military action in Syria without parliamentary approval.
Mr Williamson, who is proposing a political solution to the issue, told BBC Radio 4’s World Tonight: “That would be beyond the pale and totally unacceptable. At the very minimum, we must have parliamentary approval for any military intervention.
“But I pray and hope that it doesn’t come to that because it will be disastrous for the people on the ground and who knows where that will lead.
“My worry is that this could spiral out of control and we end up with a much wider conflagration.”
But Tory MP Chris Philp hit back and said: “What is disastrous for people on the ground, the women and children being murdered is for the West to stand aside and do nothing.”
Mr Williamson blasted: “Stop selling arms then. Stop selling arms to the Middle East.”
The Tory MP said: “We are not selling arms to Syria.”
He added: “We are not selling chemical weapons to anyone.”
The BBC host quickly shut down the interview and said: “Chris Williamson and Chris Philp, we must leave it there. Thank you both very much indeed.”
Damascus ally Russia has been at odds with the US after it warned against military action in Syria following the suspected chemical attack.
In response, the Trump administration hit new sanctions on seven Russian oligarchs, a dozen companies owned or controlled by them and 17 top bureaucrats due to the Putin regime’s support for the Syrian war.
Donald Trump also hit out at Syrian President Bashar al-Assad and allies Russia and Iran over the suspected chemical attack that killed at least 70 people on Saturday.
President Trump wrote on Twitter: “Many dead, including women and children, in mindless CHEMICAL attack in Syria. Area of atrocity is on lockdown and encircled by Syrian Army, making it completely inaccessible to outside world.
“President Putin, Russia and Iran are responsible for backing Animal Assad. Big price to pay.”
During a heated emergency session at the UN Security Council, Russia’s ambassador Vassily Nebenzia warned that the possibility of US military action was “very, very dangerous.”
