The leader of the Muslim Brotherhood, the former parliamentarian Hamdi Hassan, died in his prison cell in Al-Aqrab Prison in Cairo, late last night, Thursday.

A source from his family told Al-Jazeera Net correspondent Ahmed Ramadan that Hassan died in prison due to the deterioration of his health, "in light of the severe intransigence of the Egyptian authorities in releasing him or transferring him to a private hospital."

A human rights source also said that Hassan died as a result of deliberate medical negligence, bringing the number of deaths inside Egyptian prisons within only 12 days to 4 people, bringing the total number to 44 dead since the beginning of this year.

Ahmed Hussein, his nephew and son-in-law, confirmed - in a Facebook post - that Hamdi Hassan was buried after the authorities allowed only 10 people to attend the funeral and burial.

The human rights platform "We Record" also confirmed that the authorities handed over Hamdi Hassan's body to his family, and that he was buried amid strict security measures.
