Israeli Prime Minister Benjamin Netanyahu appealed to the International Committee of the Red Cross on Sunday for help aiding hostages in Gaza, as outrage built at videos showing two of them emaciated.
The premier's office said he spoke to the ICRC coordinator for the region, Julien Lerisson, and "requested his involvement in providing food to our hostages and... immediate medical treatment".
The ICRC said in a statement it was "appalled by the harrowing videos" and reiterated its "call to be granted access to the hostages".
In response, Hamas's armed wing said it would allow the agency access to the hostages but only if "humanitarian corridors" for food and aid were opened "across all areas of the Gaza Strip".
The Al-Qassam Brigades said it did "not intentionally starve" the hostages,
