Egyptian opposition sources said Saturday that filmmaker Shadi Habash died in a prison in southern Cairo because of deteriorating health conditions.

Axar.az reports citing Turkish media.

"Director and filmmaker Shadi Habash died at age of 24 in Tora prison, southern Cairo," singer Rami Essam said on Twitter.

Habash was arrested in March 2018, a month after Essam released a satirical song that went viral, famously known as Balaha, that criticized President el-Sisi for running for a second term.

Essam said Egyptian State Security Prosecution accused Habash of "spreading false news and joining a terrorist group."

Several opposition figures confirmed Habash’s death, including former minister Mohammad Mahsoub, legal activist Aya Hijazi and famous Egyptian director Khaled Youssef.

The Arabic Network for Human Rights Information wrote also on Twitter that Habash died “as a result of negligence and the absence of justice after spending more than two years in his dungeon."

Authorities have yet to comment on Habash's death.
