Zaki Mubarak, a Palestinian man who has died in a Turkish prison, was buried in the Gaza Strip after his body was transferred from Egypt through the Rafah crossing.
His family has expressed doubt on Turkish claims that Mubarak had committed suicide, stressing he was tortured.
Hundreds of Palestinians attended Mubarak’s funeral on Friday in the Deir al-Balah cemetery.
His brother, Zakaria Mubarak, told Al Arabiya that an Egyptian forensic team completed the autopsy on his brother's body, in preparation for a detailed report on the cause of death, saying he will be travelling to France to prepare a lawsuit against the Turkish government.
He accused Turkey of torturing and killing his brother.
Zaki Mubarak’s body was transferred last week from Turkey to Cairo. His family had insisted on carrying out an autopsy in Egypt, a request approved by Egyptian prosecutors.
After seeing his body on its arrival in Egypt, his family said it had been badly mutilated.
"His tongue was removed and we saw marks of torture on the corpse," said Abs Mubarak, his cousin, who is in Cairo.
Zaki Mubarak was arrested in Turkey last month.
