The "small improvised explosive devices" were found in A4 postal bags, the Metropolitan Police said.

The force's Counter Terrorism Command is treating it as a "linked series" and "keeping an open mind" about motives.

Irish police are assisting the Met as the Heathrow and Waterloo packages had Republic of Ireland stamps.

Heathrow's Compass Centre was evacuated after a package was reported to police at about 09:55 GMT.

The device caught fire when staff opened the bag.

A second explosive was found in the post room at Waterloo station with the same "Love & Wedding" stamps Scotland Yard said: "The packages - all A4-sized white postal bags containing yellow Jiffy bags - have been assessed by specialist officers to be small improvised explosive devices.

A Heathrow spokeswoman said the airport would support the police investigation into the "criminal act".

The Gardaí confirmed it was also assisting the Met.

Ireland's postal service identified the stamps as its "Love & Wedding" design for greeting cards, wedding invitations and thank-you cards.

The Compass Centre, which is an office for Heathrow staff rather than part of the passenger terminals, remains closed.

The picture of the jiffy bag addressed to Waterloo appears to show its sender's address as Bus Eireann, Dublin.

The operator said police had not been in touch, with a spokeswoman saying: "Bus Eireann are currently not aware of this and we have no further comment."
