The former head of the Palestinian Islamic Jihad Movement on Saturday died in the hospital where he was being treated.
The group said Ramadan Abdullah Shalah, 62, succumbed to the disease.
“We have been witnessing the struggle of the Islamic Jihad Movement since its establishment, and we remember his leadership and national stance with honor and dignity,” it said in a statement and added that Shallah always protected his Arab and Islamic identity by supporting Palestinian resistance.
Palestinian President Mahmoud Abbas issued a condolence message, according to the Palestinian official news agency, WAFA.
“By losing Shallah we lost a great national man,” Abbas said.
Shallah was born in Gaza in 1958 and became the head of the movement in 1995 after the assassination of Fathi Shaqaqi.
US authorities added Shallah to a terrorist list in 2003, and the FBI added his name to its wanted list in 2017.
Ziad al-Nakhala was chosen to lead the Palestinian Islamic Jihad Movement in 2018 because of Shallah’s illness.
