TUNIS, Sept 29, 2008 (AFP) - Georges Adda, a leading Tunisian leftist politician, died Sunday from a heart attack at the age of 92, the Movement Ettajid party said in a statement.

Born in Tunis in 1916, Adda described himself as 'anti-Zionist Tunisian Jew.' He became a leader of the Tunisian communist party and fought for independence from France, the country's former colonial master.

He was twice jailed, in 1935 and 1954, for 'continuing his fight for freedom, democracy and human rights, for defence of just causes in Tunisia and the world,' read the statement from Movement Ettajid, which evolved out of the defunct communist Party.

In his speeches and his articles, he was a strong supporter of the human rights of 'the martyr population in Palestine.'

A staunch trade unionist, he also fought for workers rights as a member of Tunisia's UGTT labour union.

Adda's son Serge Adda was a former president of French-language TV Channel TV5 Monde. He died in Paris in 2004.

Adda's burial will take place Tuesday.
