Britain’s counterterrorism police are investigating after three padded mailing bags with what appears to be small explosive devices inside were found in London.

Police said smaller bags inside the mailers enclosed the devices that “appear capable of igniting an initially small fire when opened.” Officials say the Met Police Counter Terrorism Command “is treating the incidents as a linked series.”

One mailer was found near Heathrow Airport. A building was evacuated as a precaution after the package was opened and part of it burned.

Another mailer turned up near City Airport, and the third in the mail room at Waterloo Station. The package at the rail station was not opened.
