Three British Muslim siblings were left traumatised after being escorted off a plane in London and interrogated on the tarmac as armed police kept watch, after fellow passengers accused them of being members of the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) group....

Sakina told Al Jazeera on Tuesday that as the plane was about to take off, a crew member ordered the siblings off the aircraft and escorted them down the staircase to the tarmac, where they were met by armed police and an MI5 agent who questioned them for one hour.

Earlier, two passengers - also travelling to Naples - had told authorities that the siblings had been looking at a mobile phone screen that showed either Arabic text or the words "praise be to Allah", Sakina said....

"We had nothing at all (on our phones). We don't even speak Arabic, we're (of) Indian (origin)."
