A pro-ISIS twitter account has threatened attacks at London Heathrow, LAX and New York’s JFK airports over the July 4 holiday weekend. The account said that attacks would be carried out 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. This comes as authorities in the US brace themselves for a weekend of traffic chaos as it was revealed that up to 43 million people will be travelling across the country for Fourth of July weekend.  Huge firework displays will take place across the nation, as well as concerts and family fun days.
