The Israeli army on Saturday told Palestinians in Gaza City to leave for the south before bombing a high-rise tower as its forces advance deeper into the enclave's largest urban area.

A military statement said the Israeli army designated the Al-Mawasi area of Khan Younis in southern Gaza as "a humanitarian zone," and al-Rashid Street as "a humanitarian corridor," ahead of "the expansion of the ground offensive in Gaza City" under Operation Gideon's Chariots II.

The army called on Gazans to "seize the opportunity to move to the humanitarian zone early," which is a severely overcrowded area, with tens of thousands of displaced Palestinians living in dire humanitarian conditions.

The Israeli army has bombed Al-Mawasi multiple times over the course of the war and killed hundreds of civilians sheltering there, despite labeling it a "safe zone" previously.

Israeli forces have been carrying out an offensive on the suburbs of the northern city for weeks after Israeli Prime Minister Benjamin Netanyahu ordered the military to capture it.
