Palestinians said al-Heija was considered to be close to Zakariya Zubeidi, a high-profile al-Aqsa leader in the camp who has long been on the Israeli army's wanted list.

Israel has indicated that it will continue to pursue Palestinian fighters in the West Bank despite pledging to support Abbas and the new emergency government which effectively only controls that territory.

Israel has conducted several raids around the West Bank town of Nablus over the past two days targeting fighters from the al-Aqsa Martyrs Brigades.
