Noureddine Hached has stepped down as Tunisia's ambassador to Japan in an act of solidarity with the protesters who toppled Zine El Abidine Ben Ali's government earlier this month, Arab diplomatic sources said Thursday.

Hached, 66, said he resigned to make common cause with people of Tunisia and those who have died in the protests dubbed the Jasmine Revolution, the sources said.

The ongoing clashes between protesters and riot police have resulted in numerous fatalities.

Hached's late father was the founder of a labor union that has played a pivotal role in the political upheaval. He was assassinated after leading a resistance movement when Tunisia was under French colonial rule.
