The Fatah Movement is headed by Palestinian Authority Chairman Mahmoud Abbas.

An announcement published by the "al-Aqsa Martyrs' Brigades - Falastin/ Beit Omer the Fast Response," called on "all of the fighters in the West Bank" to move to "general alert" mode.

"We have received the instructions. We hereby declare the escalation of the general alert situation of all our fighters to the highest level, which is that of open warfare," the group wrote on Telegram.

"We call on all of our fighters and military cells, in every place in the West Bank, to attack the Zionist enemy and all of its components, including within the fragile heart of the entity, Tel Aviv.

"This is a revolution and an armed intifada which will be ongoing until victory. Mercy to our heroic martyrs, recovery to our heroic injured, and freedom to our heroic prisoners."
