The Islamic Jihad (Holy War) announced on Saturday that the movement would demand the Palestinian security apparatuses to follow collaborators with Israel and impose security on the Palestinian lands.
Khaled al-Batsh, a senior Jihad leader, told Xinhua before joining a meeting of Prime Minister Ahmed Qurei and different national and Islamic factions at the headquarters of the executive committee of the Palestine Liberation Organization (PLO) in the Gaza Strip.
Batsh said "there's fear that the Israeli army would attack the Palestinian people in case Arafat passes away. We have to be ready for such a situation."
The French hospital, where Palestinian leader Yasser Arafat is receiving intensive care, said Friday that his health "has not deteriorated and is considered stable".
Conflicting reports emerged earlier on the health condition of Arafat, with some saying Arafat was brain dead and on life support machines.
