US State Department: United Kingdom travel advisory at Level 2 'Exercise Increased Caution'
The U.S. Department of State maintains a Level 2 'Exercise Increased Caution' travel advisory for the United Kingdom due to terrorism, citing the risk of terrorist violence including attacks and other activity. The advisory also notes the risk of isolated violence by dissident groups in Northern Ireland, which mainly target police and military. Petty crime is common, especially in popular tourist locations, and most crimes against foreigners are crimes of opportunity such as purse or cellphone snatching and pickpocketing.
