Four members of the anti-Fascist group TIGR were executed outside the village of Basovizza near Italy's Trieste by Fascists on this day in 1930 after being found guilty of a bomb attack on the Il Popolo di Trieste paper.

An annual ceremony will be held at the memorial to the victims in Basovizza, organised by a committee of the National and Study Library in Trieste.

The ceremony is to be addressed by Gorizia-based writer and journalist Andrea Bellavite, Croatian writer Milan Rakovac and Trieste-based Slovenian politician and writer Rafko Dolhar.

Another ceremony was meanwhile held in Ljubljana's Congress Square on Sunday morning by an outfit called the 13 May Movement. The commemoration also remembered other victims of Fascism.

Around 50 people turned out in the centre of the capital to pay their respects to those who died under Italian Fascist authorities. Head of the movement Vili Kovačič called for 13 May, the day in 1941 that saw the first armed battle against the occupying forces, to be declared a national holiday.

Kovačič said that the role of TIGR and the importance of the broader anti-Fascist movement in Slovenia was not well understood among the masses. Declaring a holiday and other symbolic gestures, such as erecting a statue by the Presidential Palace in Ljubljana, would help raise awareness, he argued.

Slovenia has failed to take advantage of the message of its anti-Fascist past by promoting itself as the first nation to stand up to the radical nationalist ideology, Kovačič told the gathering.
