Egypt's first democratically elected president Morsi buried east of Cairo after courtroom death

Egypt's first democratically elected president Mohammed Morsi was buried under heavy security early on Tuesday, 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. Massive protests grew against their rule, until the military — led by then-Defense Minister Abdel-Fattah el-Sissi — ousted Morsi in July 2013, dissolved parliament and eventually banned the Brotherhood as a "terrorist group."

In August 2013, troops descended upon protest camps filled with Morsi's supporters, killing hundreds in Cairo's Rabaa al-Adawiya Square and elsewhere in a single day.

El-Sissi was elected president and re-elected in 2018 in votes human rights groups sharply criticized as undemocratic. He has waged a ferocious crackdown that crushed the Brotherhood but also almost all other dissent, arresting tens of thousands, banning protests and silencing most criticism in the media.

Since his ouster, Morsi and other Brotherhood leaders have been put on multiple and lengthy trials. Morsi was sentenced to 20 years in prison on charges of ordering Brotherhood members to break up a protest against him, resulting in deaths. A death sentence against him was overturned and commuted to life imprisonment while multiple cases were still pending. Monday's session was part of a retrial on charges of espionage with the Palestinian Hamas militant group.

Hamas is part of the pan-Arab Brotherhood movement but has taken measures in recent years to reconcile with the current Egyptian authorities, removing from its founding charter parts that stressed explicit affiliation with the Brotherhood.

Human Rights Watch on Tuesday urged the U.N. human rights council to investigate the circumstances of Morsi's death and specifically, Egyptian authorities for "their mistreatment" of Morsi "after years of insufficient access to medical care" while in prison.

The New York-based group's Sarah Leah Whitson said Morsi's treatment in prison was "horrific, and those responsible should be investigated and appropriately prosecuted."

"At the very least, the Egyptian government committed grave abuses against Morsi by denying him prisoners' rights that met minimum standards," she added.

In audio leaked from a 2017 session of one of his trials, Morsi complained that he was "completely isolated" from the court, unable to see or hear his defense team, his eyes pained by lighting inside the cage.

"I don't know where I am," he is heard saying in the audio. "It's steel behind steel and glass behind glass. The reflection of my image makes me dizzy."
