Terrorists are very likely to try to carry out attacks in the USA. Attacks could be indiscriminate, including in places visited by foreigners. You should monitor media reports and be vigilant at all times.
The main threat comes from individuals who may have been inspired by terrorist groups, including Daesh (formerly referred to as ISIL) and al Qaeda, to carry out so-called ‘lone actor’ attacks targeting public events or places, as demonstrated by attacks in New York, New Jersey and Minnesota over the weekend of 17-18 September 2016, Orlando on 12 June 2016 and San Bernardino on 4 December 2015, among others. Attacks could take place with little or no notice.
There’s a heightened threat of terrorist attack globally against UK interests and British nationals, from groups or individuals motivated by the conflict in Iraq and Syria. You should be vigilant at this time.
The US Department of Homeland Security (DHS) provides public information about credible threats. Expect an increased presence of law enforcement and tight security at public places and events. This may include a heavy police presence, additional restrictions and searches on bags, and the use of screening technologies. For all current alerts within the United States and its territories, visit the DHS website.
