Passengers have been evacuated from Heathrow Airport's Terminal Three amid reports of a suspect package being investigated by police.
The current nature of the situation is not yet confirmed but there have been reports of a bomb threat, Air Live said.
Posts on social media report that a suspicious item was found inside a passenger's baggage with police and other emergency services in attendance.
Heathrow is the UK's busiest airport, typically seeing more than 200,000 travellers pass through each day.
Today's disruption comes two months after the airport was shut down all day after a devastating electrical fire.
