Threat levels

Threat levels are designed to give a broad indication of the likelihood of a terrorist attack:

• LOW means an attack is highly unlikely
• MODERATE means an attack is possible, but not likely
• SUBSTANTIAL means an attack is likely
• SEVERE means an attack is highly likely
• CRITICAL means an attack is highly likely in the near future

The following websites provide information on how you can increase your safety and know what to do if you see or hear something that doesn't feel right:
