Benjamin Netanyahu is reportedly planning to expand the conflict in Gaza to bring home hostages after Hamas released chilling images of emaciated captives.

A diplomatic source quoted in Hebrew media on Sunday revealed the Israeli Prime Minister is 'pushing for the release of the hostages through decisive military victory, combined with the entry of humanitarian aid to areas outside the combat zone, and, as much as possible, outside of Hamas control'.

The distraught families of the hostages have sharply rebuked the suggestion, arguing expanding the conflict could endanger those still in Hamas captivity.

Netanyahu himself appeared visibly shaken in a video statement after harrowing footage emerged of two hostages, Evyatar David and Rom Braslavski, both looking skeletal and pale in what appeared to be an underground tunnel.

David, digging what he believed to be his own grave, was heard begging for his life.
