Labour MP Andy Burnham has warned the public must remain vigilant if it is confirmed that the crash of EgyptAir flight MS804 was caused by terrorism.
The aircraft vanished early on Thursday morning while on an overnight flight from Paris Charles De Gaulle to Cairo. According to officials, debris from the Airbus A320 has now been found 180 miles off the coast of the Egyptian city of Alexandria.
The cause of the crash is currently unknown, but French President Francois Hollande said "no hypothesis could be ruled out". Officials in Egypt have announced that the "most likely cause" of the crash was a terror attack.
With speculation growing of terrorism being the cause, the shadow home secretary expressed his concerns.
"It's incredibly worrying," he told Paul Ross. "Not only are we seeing terrorism taking a new approach in Paris and Brussels, we still have the threat at our airports.
"My concern would be it stretching the authorities to the limit. It is speculation, but if it [terrorism] is what happened here, this is a threat which just grows and grows."
An aviation expert told Julia Hartley-Brewer yesterday that security concerns at UK airports would rise if Flight MS804 was downed as a result of a terror attack. While the MP for Leigh reassured listeners not to "rush to judgement", he did stress the importance of remaining alert to dangers.
"Airport security is incredibly tight these days," Burnham said. "We have to be aware there is the potential for terrorism in a whole range of ways. We have to be viligant."
