A series of mailed improvised explosive devices have been found at a series of key transport infrastructure sites across London, with transport workers placed on high alert for more.

Londons Metropolitan Police, who as well as taking responsibility for London policing also lead the UK’s counter-terrorism police force, said they launched an investigation Tuesday after three suspicious packages were discovered. The force said they were treating the packages as linked.

In an internal message seen by Breitbart London Tuesday, transport workers were warned “padded envelopes… unusual items” had been delivered to several transport operators through the regular Royal Mail post and that one had detonated. Staff, and particularly ones in “major operational buildings” were warned to evacuate in the case of suspicious packages being found.

Police said one package that had been opened by staff in Hounslow had ignited and burnt the packaging. There have been no injuries.

The impacted locations are the postal sorting office at London Waterloo railway station, London Heathrow airport, and London City airport. While some trains were impacted by earlier investigations, services have now resumed.
