Egypt's former President Mohamed Morsi, the country's first democratically elected head of state who was later ousted from power, collapsed and died during a court session Monday.
Officials said the 67-year-old had just addressed the court during his trial on espionage charges when he collapsed. They say Morsi spoke for five minutes from the glass cage he is kept in during the trial and a few minutes later fell to the ground.
State television said Morsi was taken to the hospital, but was dead on arrival. Morsi, long a top figure in the Islamic group, the Muslim Brotherhood, was overthrown as president in 2013 by Egypt's military after mass protests against his rule.
The Muslim Brotherhood was later outlawed by the military and Morsi arrested. The former president has faced multiple trials since his ouster on charges that included spying for Iran and Qatar and for the killing of Egyptian protesters during demonstrations in 2012.
He has been in prison since 2013 and was on trial Monday on charges of espionage related to suspected contacts with the Palestinian group Hamas, which has close ties to the Muslim Brotherhood.
The Muslim Brotherhood's Freedom and Justice political party said in a statement published on its website Monday that Egyptian authorities are responsible for Morsi's "deliberate slow death" because they "withheld medication and gave him disgusting food. They did not give him the most basic human rights."
The leading member of the Muslim Brotherhood in London, Mohammed Sudan, said, "This is premeditated murder. This is slow death."
Human Rights Watch has described the charges against Morsi as political. The group's Middle East director, Sarah Leah Whitson, said Monday on Twitter that Morsi's imprisonment was "cruel and inhumane" and said he was "deprived of family visits and medical care."
Amnesty International called for Egyptian authorities to conduct an impartial investigation into the circumstances of Morsi's death, including the medical care he was receiving.
Egypt's chief prosecutor said a team of forensic experts will examine Morsi's body to determine the cause of death. Turkey's President Recep Tayyip Erdogan, who was a strong ally of Morsi when he was in power, paid tribute to the former president on Monday calling him a "martyr," while calling current Egyptian President Abdel-Fattah el-Sissi "cruel."
Qatar's ruler Sheikh Tamin bin Hamad al-Thani, another backer of Morsi, tweeted his condolences, saying he received the news of Morsi's death with "deep sorrow."
Morsi's rise, fall
Morsi was elected president in 2012 in Egypt's first free elections following the ouster the previous year of longtime leader Hosni Mubarak. Morsi promised a moderate Islamist agenda and a new democratic era, but his time in power proved difficult, with critics accusing him of trying to amass power and impose the Muslim Brotherhood's conservative brand of politics on the country.
After his arrest, Morsi gave angry speeches in court and has continuously insisted he remains Egypt's legitimate president. His speeches led judges to order him kept in a glass cage during court sessions where they could turn off his audio.
