U.K. police have opened a counterterrorism investigation after three suspicious packages containing what appeared to be explosive devices were discovered at major transit hubs in London on Tuesday. Small improvised explosive devices were found at buildings at Heathrow Airport, London City Airport and Waterloo train station, Metropolitan Police said. "The packages — all A4-sized white postal bags containing yellow Jiffy bags [padded envelopes] — have been assessed by specialist officers to be small improvised explosive devices," police said in a statement. All three white postal bags that were found contained yellow bags thought by specialist police to be small improvised explosive devices. Around noon police were called to a report of a suspicious package at offices at City Aviation House at London City Airport.
