Daily Mail reports:
A pro-ISIS twitter account has threatened attacks at London Heathrow, LAX and New York’s JFK airports on the July 4 weekend.
The account threatened attacks on planes ‘flying from Heathrow [Airport] to the US’ and warned that ‘there will be a device placed in either Heathrow, LAX or JFK airports.’
The threat was revealed by SITE Intelligence Group – the world’s leading non-governmental counterterrorism organization – on its website.
The group is directed by founder Rita Katz, who has tracked and analyzed global terrorism and jihadi networks for nearly two decades.
She is well-recognized as one of the most knowledgeable and reliable experts in the field and has received special recognition from FBI Director Robert Mueller for her ‘outstanding assistance to the FBI in connection with its investigative efforts.’
law enforcement and members of the public must remain vigilant. … The FBI asks members of the public to maintain awareness of their surroundings and to report any suspicious activity to law enforcement,’ an FBI spokeswoman said
