More than 20 passengers were injured, some suffering severe burns, in an early morning explosion on a London Underground train in what police described as a “terrorist incident,” the fifth attack in six months in Britain. Emergency services were called around 8:20 am (0720 GMT) after the explosion at Parsons Green station in a leafy southwestern suburb which police counter-terror chief Mark Rowley said had been caused by an “improvised explosive device.” / AFP PHOTO / @sylvainpennec / HO / ===RESTRICTED TO EDITORIAL USE – MANDATORY CREDIT “AFP PHOTO / HO / @sylvainpennec – NO MARKETING NO ADVERTISING CAMPAIGNS – NO ARCHIVES – DISTRIBUTED AS A SERVICE TO CLIENTS
