The London Metropolitan Police’s counter-terrorism command unit has launched an investigation into found explosives, which were sent in small packages to buildings at or near Heathrow Airport, London City Airport and Waterloo train station.
All the devices were judged to be viable, and in one instance, the package burst into flames when staff opened it. No one was hurt.
The Irish police are also assisting with the investigation, a spokesperson for An Garda Siochana, Ireland’s national police force said.
British and Irish news outlets have reported that at least two of the packages had stamps.
The Metropolitan Police said that the incidents appeared to be part of a “linked series.”
Sadiq Khan, the Mayor of London, paid tribute to police for their response.
“Counter Terrorism Command has launched an investigation after three suspicious packages were found at locations around London today — thankfully there have been no injuries,” Khan said in a statement.
“I would like to thank first responders for their swift actions to keep Londoners safe.”
