While he held no official position in the north African country under his father Muammar Gaddafi’s rule, he had been described as Libya’s de facto prime minister, cultivating an image of moderation and reform prior to the 2011 Arab Spring revolt.
That reputation soon collapsed when he promised “rivers of blood” in the face of the uprisings.
He was arrested in November 2011 in southern Libya following a warrant by the International Criminal Court (ICC).
He was sentenced to death in 2015 after a speedy trial but was granted amnesty.
In 2021, he announced he would run for president, but those elections were indefinitely postponed.
Libya expert Emadeddin Badi said Seif al-Islam’s death was “likely to cast him as a martyr for a significant segment of the population, while also shifting electoral dynamics by removing a major obstacle to presidential elections”.
“His candidacy and potential success had been a central point of contention,” Badi wrote on X.
Muammar Gaddafi’s last spokesman, Moussa Ibrahim, also posted on the social network: “They killed him treacherously. He wanted a united, sovereign Libya, safe for all its people.
“I spoke with him two days ago. He spoke of nothing but a peaceful Libya and the safety of its people.”
Libya has struggled to recover from chaos that erupted after a Nato-backed uprising in 2011 overthrew Muammar Gaddafi.
Libya remains divided between a United Nations-backed government based in Tripoli and an eastern administration backed by Khalifa Haftar.
