CAIRO (AP) — Egypt’s first democratically elected president, Islamist leader Mohammed Morsi, was buried under heavy security early today, a day after his dramatic collapse and death inside a Cairo courtroom, a member of his defense team said.

Morsi’s family attended funeral prayers in the mosque of Cairo’s Tora prison, followed by the burial at a cemetery in the city’s eastern district of Nasr City, said Abdul-Moneim Abdel-Maqsoud, a member of Morsi’s defense team.

Morsi’s son, Ahmed, said security agencies refused to allow Morsi to be buried at the family’s cemetery in his hometown in Sharqia province, and instead had him interred at a cemetery dedicated to prominent Islamists in Cairo.

Security agents turned reporters away from the cemetery, banning them from taking photographs of the funeral. Reporters were also barred from traveling to Morsi’s hometown.

Morsi, 67, hailed from Egypt’s largest Islamist group, the now outlawed Muslim Brotherhood, and was elected president in 2012 in the country’s first free elections following the ouster the year before of longtime autocratic leader Hosni Mubarak.

The military toppled Morsi in 2013 after massive protests and crushed the Brotherhood in a major crackdown, arresting Morsi and many others of the group’s leaders.

During his years in prison, Morsi, who was known to have diabetes, was often held in solitary confinement and was largely barred from receiving visitors. His family was only allowed to visit three times. While in detention, Morsi continued to appear in court on a range of charges.

In early court sessions he gave angry speeches until judges ordered him kept in a glass cage where they could turn off his audio.

Morsi’s Brotherhood accused the government of “assassinating” him through years of poor prison conditions. The group demanded an international investigation into Morsi’s death Monday and called on Egyptians to protest outside Egyptian embassies across the world.

Late Monday, Egypt’s chief prosecutor said Morsi’s body would be examined to determine the cause of his death. State TV, citing an unnamed medical source, said he died after suffering a heart attack.

Morsi collapsed just after he had addressed the court, speaking from inside the glass cage and warning that he had “many secrets” he could reveal, a judicial official said, speaking on condition of anonymity under regulations.

In his final comments, Morsi continued to insist he was Egypt’s legitimate president, demanding a special tribunal, one of his defense lawyers, Kamel Mandour told The Associated Press. State TV said Morsi died before he could be taken to hospital.

It was a dramatic end for a figure central in the twists and turns taken by Egypt since its “revolution” — from the pro-democracy uprising that in 2011 ousted Mubarak, through controversial Islamist rule and now back to a tight grip under the domination of military men.

The Brotherhood won the elections held after Mubarak’s fall, considered the first free votes the country had seen. First, they gained a majority in parliament, then Morsi squeaked to victory in presidential elections held in 2012, becoming the first civilian to hold the office.

Critics accused the Brotherhood of using violence against opponents and seeking to monopolize power and Islamize the state.
