Gunmen have wounded a Palestinian reformer in a gun attack in the West Bank.
There was no immediate claim of responsibility for the attack on Nabil Amr, who was hit twice in the right leg by bullets fired into his home in the West Bank city of Ramallah. Doctors said his injuries did not appear to be life-threatening.
Palestinian police said they had opened an investigation into the night-time shooting, carried out against the backdrop of a leadership crisis in the Palestinian Authority over demands for democratic reforms.
Arafat is facing the stiffest test of his leadership since Palestinians obtained limited self-rule from Israel in Gaza and the West Bank a decade ago. Some fear the strife could eventually escalate into civil war.
"We were sitting inside when someone shot at him from the window," the lawmaker's son, Marwan, told Reuters.
Palestinian sources said Amr, a former information minister, has long been at odds with Arafat over the pace of reforms in institutions seen as out of touch.
Amr, 47, was shot minutes after returning home from a television interview in which he criticised Arafat's performance as president. His residence has been shot at in the past.
Prime Minister Ahmed Qurie submitted his resignation to Arafat on Saturday, complaining about chaos in Gaza, where militants demanding anti-corruption moves have fought Palestinian security forces.
Qurie, who has said he would remain in office for now after Arafat rejected his resignation, is frustrated over Arafat's refusal to allow him to reform Palestinian institutions and a jumble of security services ridden by cronyism.
