The BBC presenter faced accusations of being “weak” and “out of her depth” from social media users. Ms Bruce hosted a special Afghanistan focused edition of Question Time, after the country fell to the Taliban.
On August 15 the Taliban stormed Kabul, the capital of Afghanistan, with westerners and their allies forced to flee to the airport.
The Question Time panel, including James Cleverly, a Foreign Office minister, and shadow foreign secretary Lisa Nandy, debated the issue on Thursday.
The line up also contained former international development secretary Rory Stewart, and journalists Nelufar Hedayat and Mehdi Hasan.
Ms Bruce soon came under fire over her performance in the chair, and became a trending topic on UK Twitter.
One critic wrote: “How weak is Fiona Bruce?
“James Cleverly just rolled right over her and it was left to an audience member to stop him and put him straight. Farcical.”
Another asked: “Why does Fiona Bruce continually try to challenge and interrupt Lisa Nandy but not James Cleverly, despite him never answering the question?”
A third said: “Fiona Bruce is so out of her depth leading Question Time.

He replied: “I’m not able to give that commitment right now but there is always an after-action review.
“That will of course happen with this and questions will be asked of everyone involved in the decision politically, militarily, diplomatically.”
Speaking for Labour, Ms Nandy criticised the Government over its level of preparations for withdrawal.
She said: “Our government had 18 months to prepare, 18 months ago in Doha there was an agreement that the US would be leaving and Joe Biden has always made clear he would respect that agreement.”
However she also admitted Mr Biden’s withdrawal undermined the Afghan army, commenting: “The decision by Joe Biden to put a firm end date on the withdrawal obviously helped to motivate the Taliban, and give them a signal that they could advance across the country.
“It had a huge impact on the morale of the Afghan forces and really undermined the efforts that had been made to try and strengthen their resilience.”
Last year Donald Trump signed a deal with the Taliban to withdraw US troops by May 2020.
In return the Taliban said they would begin negotiations with the Afghan government, which they have now deposed, and not harbour Al-Qaeda terrorists again.
Mr Biden delayed the final pull out, so it would coincide with the 20th anniversary of 9/11.
The Taliban provided sanctuary to the Al-Qaeda terrorists who attacked New York and Washington DC in 2001.
