After a group of activists hoodwinked the Heathrow airport security and entered the runaway in the wee hours of Monday, there are fears being raised that even terrorist groups such as the Islamic State (Isis) could carry out an attack on the UK's busiest air terminal.

Thirteen climate change activists, from the direct action group, Plane Stupid, stormed the Heathrow Airport runway at around 3:30am (local time) on Monday to protest the proposed expansion plan of the airport, Sky News reported.

The activists, who locked themselves at the runaway, had to be forcefully removed by the police. The incident led to cancellation of 22 flights, while several flights were delayed. Seven British Airways flights from Heathrow were among those cancelled.

Scotland Yard confirmed to The Telegraph that six of the protesters were arrested under various sections of the Aviation Act offences.

The incident, however, has raised a major concern among security experts, who fear that terrorist groups could "easily" be able to carry out an attack on the airport. It is reported that the activists entered the Heathrow runaway after cutting through the airport's steel fences.

Azfal Ashraf, a consultant at the Royal United Services Institute, a defence and security think-tank told Express.Co.Uk the incident "does raise questions" about security at the airport.

"If a terrorist group came up to the fence it would take a few minutes to cut through. It's very easy to get to a fence before the police are able to react," Ashraf added.

Many even took to Twitter to criticise the local security at the Heathrow airport, especially as it took the personnel several hours to evacuate the protesters from the airport. And some of them even raised fears that militant outfits such as the Isis could storm the airport without much difficulty.

So a load of crusties can get onto a live runway at Heathrow. Great security lads. Imagine if it were a couple of reps from ISIS.
