Good Morning Britain were live from the English Channel on Tuesday morning as they observed 13 migrants making their way over to the UK from France.
Journalist Pip Tomson explained how the ITV crew had to alert UK officials after a French navy warship left the passengers stranded at the border.
As the dingy moved along the water in the background, Pip told viewers: "I think there’s 13 people onboard on this inflatable dingy that’s really only for six or seven.
"Now, although conditions do look ideal today for making this journey today, it is still very, very dangerous indeed. There are lots of other ships out and about, it only needs a bow wave and that could capsize them."
Pip continued: "Border Force are very busy this morning, they are dealing with other incidents, so as soon as we saw these passengers we alerted the coast guard. This was at the English French border about an hour or so ago.
"At that point they were being tailed by a French warship. That French warship we believe took them to the border, maybe saw us, maybe didn’t, maybe saw us and thought then we would observe from a distance," she added.
Later on in the show, Border Force were filmed approaching the dinghy on a jet ski and Pip explained that GMB had made the decision to distance themselves.
The scenes come after it was reported that at least 430 migrants made the risky journey across the 21-mile Dover Strait amid 24C heat on Monday to the safety of Britain.
The figure passes the previous daily high of 416 set in September 2020, according to data compiled by the PA news agency.
High numbers of crossings have continued this summer despite Home Secretary Priti Patel's vow to make the Channel crossings "unviable".
In Dungeness in Kent, around 50 people were seen landing on a beach after crossing aboard in a single dinghy.
Some raised their hands in celebration as they stood on the beach, while others sat down on the shingle shoreline amid 24C sunshine.
Also on Monday, plans for sweeping reforms of the asylum system, dubbed the anti-refugee Bill by critics and campaigners, were debated again in Parliament.
Theresa May sounded warnings over the prospect of the UK sending asylum seekers to Australia-style offshore processing centres.
The former prime minister said she considered the idea when home secretary but rejected the option due to "practical concerns".
Good Morning Britain airs weekdays at 6am on ITV.
