One eyewitness, Nicole Kyle, was walking home when she saw police head towards Buckingham Palace.
The 25-year-old said: "I was walking toward The Mall and St James's Park when I saw police rush down toward the palace in great numbers.
"As we got further down The Mall we saw armed police outside a police van, at which point we were able to walk closer to the palace still, where we were eventually stopped by a cordon.
"All we were told was that there's been an incident.
"A few minutes later police came by to have us clear the area and move further away from the palace."
Another witness, Natalie Wood, wrote on Twitter: "Police still being called into Buckingham Palace. Everything on lockdown, heavily armed police seem calm."
A Buckingham Palace spokeswoman said she would not comment on security issues.
