French President Nicolas Sarkozy should use his visit to Syria on September 3 and 4, 2008, to raise human rights concerns with President Bashar al-Asad, Human Rights Watch said today. In particular, Sarkozy should urge Asad to release activists detained solely for exercising their rights to freedom of expression and association. He should also ask Asad to make public all information on the violent suppression of a riot at Sednaya prison in July 2008.
