He said his assassination pushes the Palestinian people "to remain more steadfast in the face of the (Israeli) occupation, and the necessity of achieving the unity of the Palestinian forces and factions."

Mustafa Barghouti, head of the Palestinian National Initiative party, mourned Haniyeh, and condemned Israel for committing such "heinous crime."

"The Palestinian people today lost a brave patriot leader, known for his integrity and straightforwardness, and for his honest care to national unity," Barghouti said in a statement.

The Fatah Movement, led by President Abbas, also condemned Haniyeh's assassination, defining it as a coward act.

The Palestinian resistance group Hamas announced early Wednesday that Haniyeh was killed in an Israeli airstrike on his residence in the Iranian capital Tehran.

Israel has made no immediate announcement about the assassination
