A protester took down the Libyan flag from the embassy in London, replacing it with the national flag from the pre-Gaddafi era.
The man was unchallenged as he scaled the building, and applauded by his fellow protesters below.
Pressure is building on Col Muammar Gaddafi to step down as protests continue in Libya and around the world.
