Israel’s move to a new stage in the conflict comes after its initial bombardment and a ground invasion that began on Oct 27. Air and artillery strikes have continued to pound the entire enclave during that time, leaving much of it in ruins, Reuters reports.

With Israeli tanks and troops having overrun most of northern Gaza, while still pushing into the centre and parts of the south, Hamas is responding with guerrilla-style ambushes from tunnels and bunkers in the enclave’s narrow streets.

Hamas seized 240 hostages on Oct 7 and Israel believes 129 are still held in Gaza after some were released during a brief truce and others killed during air strikes and rescue or escape attempts. Qatar and Egypt are seeking to negotiate a new truce and hostages deal.

Avi Dichter, a member of Israel’s security cabinet, said on Kan Radio that hostages could only be freed by putting “massive” pressure on Hamas and allied groups. “Without Hamas’ terrorist infrastructure being destroyed and its governance capabilities toppled, the war will not end,” he said.
