Speaking in a ceremony held to mark the 28th anniversary of the establishment of Hamas, Khalil Hayya added that the Intifada needs unity among all Palestinian groups.
In October, senior Hamas leader Ismail Haniyeh declared the ongoing unrest in the occupied territories and the West Bank to be an Intifada.
"We are calling for the strengthening and increasing of the intifada. It is the only path that will lead to liberation. Gaza will fulfil its role in the Jerusalem intifada and it is more than ready for confrontation,” Haniyeh said at the time.
Meanwhile, tensions between Palestinian protesters and Israeli forces in the occupied West Bank and the Gaza Strip are showing no sign of abatement.
The wave of unrest was triggered by Israel’s imposition in August of restrictions on the entry of Palestinian worshipers into the al-Aqsa Mosque compound in East al-Quds.
Palestinians are also angry at increasing violence by Israeli settlers, who frequently storm the al-Aqsa Mosque, the third holiest site in Islam. The Palestinians say the Tel Aviv regime seeks to change the status quo of the compound.
