A group including labour unions and high number of anti-capitalists gathered in Enniskillen town and walked to Lough Erne Resort where the G8 Summit takes place.
Several people set a British flag on fire before starting walking as they were carrying posters against the summit and chanting slogans too.
A group of 100 to 150 people got over the security fence in Lough Erne where tight security measures had been taken previously. Yet, the police forces did not let the group move forwards.
Anti-capitalists have been holding various demonstrations in Belfast, London and Enniskillen since last week against G8 Summit.
The last march took about 10kms.
