Egypt’s former president Hosni Mubarak, who was toppled in 2011 as part of the country’s revolution, has died, according to reports.

The 91-year-old is said to have been in hospital for several weeks before his death, with his son Alaa tweeting in January about his father undergoing surgery.

Quoting his lawyer Farid al-Deeb, the Egyptian Independent reported on Monday that Mubarak had been in an intensive care unit since last month after a bout of fatigue.

It added that he also suffered complications after undergoing surgery on his intestines.

Mubarak, known by his nickname as the modern-day “pharoah”, ruled Egypt as an autocrat for three decades from 1981, and was jailed for years after the Arab Spring uprising that ended his rule.

He was given a life sentence for the deaths of anti-government protesters at the heart of the revolution, but was released in 2017 after being acquitted for the most of the charges.

Before becoming the country’s fourth president, he served in the Egyptian air force as a bomber pilot and notably as its commander during the 1973 Arab-Israeli war.
