Watch the moment GB News star is confronted by pro-Iran protesters: 'I'm trying to do my job!'

Delivering his report from the pedestrian pathway, Alex was suddenly covered with two placards from protesters on the wrong side of the barrier.

Alex told the pro-Iran demonstrators: "If you want to protest, you should be on that side of the barrier. This is for pedestrians."

The protesters failed to stop their antics, covering Alex's face a second time, forcing the presenter to push the signs away from him.

He told GB News host Andrew Pierce: "We're obviously trying to be here, and trying to stop us doing our job.

"Now, this is of course a pedestrian part of the protest, so what they're not allowed to do is they shouldn't be actually coming up to me here."

Alex warned the protesters again, making clear: "You guys need to be on that side of the barrier or the police will arrest you, so please move along."

Covering Alex's face a third time, the GB News star reiterated to them and to People's Channel viewers that he is "just trying to report what's going on in Britain".

Alex said: "This is the sort of stuff we get when we're trying to just report the news, just trying to report the news and report the protest.

"Of course, these gentlemen here are actually not allowed to be legally doing this, they could get in a lot of trouble and they should be on that side of the protest."

The gentlemen finally retreated and walked away from Alex, causing him to stress that their actions towards him are similar to what he has been faced with the entire day.

He said: "These gentlemen are free to protest, and now they're moving along, great. But that's the sort of stuff I've been getting today, Andrew.

"Of course, lots of people are very, very upset about us being here, but this is what we do, we report both sides of the story."

Alex was then silently approached by another gentleman, who appeared to be standing next to and filming the GB News star.

Recognising the man from a previous protest, Alex told GB News viewers: "You might notice I've got a friend here as well. He was here last week at the protest too, Andrew.

"It's a very, very, very, very tense atmosphere here today. It's hard for me to do my job, just to report the news."

Addressing the man stood next to him, Alex explained: "And his gentleman is back here again today. GB News viewers will be familiar with him from last week.

"Look, I'm just here trying to do my job. I want to hear what these people have to say, I want to report the news, and that is what we try to do as GB News, report both sides fairly, which is what we did last weekend. However, we are being stopped doing that this week."

Thousands of demonstrators gathered in the capital for Quds Day, an annual pro-Palestinian event that opposes Israel and Zionism.

Counter-protestors were also gathered on the north bank of the River Thames, with some displaying flags of Israel and Iran before the Islamic revolution.
