Amnesty International claims Ibrahim Halawa may face the death penalty in Egypt.

Today marks the 777th day of the 19-year-old's detention after his arrest in Cairo back in 2013.

Following numerous postponements, Ibrahim is due to stand trial again on Sunday.

His family will stage a demonstration to call for his immediate and unconditional release at the Spire in Dublin this afternoon at 3 O'clock.

Colm O'Gorman is from Amnesty International:

Ibriham, who Amnesty has named an International Prisoner of Conscience, is from Firhouse in Dublin and was holidaying in Egypt when he was arrested.

Ibrahim Halawa was 19 when he was arrested

He and his sisters were forced to seek sanctuary in the Al Fateh mosque after violent clashes between supporters of ousted president Mohammed Morsi and the security forces.

They were subsequently jailed in Tora prison, before the sisters were released and returned to Ireland. 

Sunday's court date is his 8th trial date.

Ibrahim's father Sheikh Hussein Halawa is the imam of Ireland's largest mosque.
