“We stress the need to regain Palestinian unity and end the policy of exclusion and unilateralism by the leadership of the Palestinian Authority and its hijacking of Palestinian institutions,” said Masri.
Khader Habib of Islamic Jihad, a Hamas political ally, accused Abbas of “holding the PNC meeting to stress his exclusion of all those who oppose him”.
“The president is keen for the conference to bring about only decisions that suit his own project,” Habib told Reuters.
Hamas and Islamic Jihad oppose Abbas’ strategy of peace talks with Israel. However, diplomacy has been on hold since 2014 and many Palestinians’ views have hardened over U.S. President Donald Trump’s recognition late last year of Jerusalem as Israel’s capital.
The PNC last met in extraordinary session in 2009 to replace several members of the PLO’s Executive Committee. It last held a regular session in 1996.
Political analysts in Gaza said a PNC meeting without wide factional representation would weaken the legitimacy of any decisions it may take.
Earlier on Sunday dozens of masked youths gathered on the Palestinian side of the Gaza Strip’s main crossing with Israel, threatening to block any PNC official from leaving for the West Bank to attend Monday’s session.
