In 2000, Dalila was active in the "
Damascus Spring", the title used for the period of political activism that followed following the death of former president Assad in June 2000 and the succession to the presidency of his son,
Bashar al-Assad. During a general crackdown on the Damascus Spring activists, Dalila was arrested in Damascus on 9 September 2001, reportedly following a lecture advocating greater democracy and transparency in government and an end to corruption. France and the U.S. objected to Dalila's imprisonment and pressed for his release. President Assad responded that the complaints amounted to foreign interference in Syrian domestic affairs. Dalila was later adopted by
Amnesty International as a
prisoner of conscience.
PEN American Center also protested his sentence, stating that his trial "did not comply with international standards." During his imprisonment, Dalila suffered from
diabetes and heart disease, undergoing a heart surgery; both conditions were reportedly worsened by the poor conditions of his confinement. He began a hunger strike to protest these conditions in July 2005. In May 2006, he also suffered a stroke. When he was released from prison on 7 August 2008 by presidential amnesty, he was the longest-serving prisoner from the Damascus Spring. He had served seven years of his ten-year sentence, the majority of which was spent in solitary confinement. == Role in Syrian uprising ==
