Israel has stepped up efforts to retrieve the remains of the final Israeli hostage in Gaza, Staff Sgt. Maj. Ran Gvili, by detaining a terrorist who was involved in his abduction and knows his whereabouts, Asharq Al-Awsat reports.

The action coincides with a stalling of the cease-fire agreement, with Israeli sources saying they believe Hamas and Palestinian Islamic Jihad are aware of the location of the remains, and the terror groups claiming they are unable to find them.

According to the Saudi report, the detained Palestinian Islamic Jihad member was seized in central Gaza City, near Palestine Square. The IDF declined to comment on the report, Army Radio said.
