Prime Minister Naftali Bennett responded Tuesday to Hamas' release of a video purportedly showing captive Israeli citizen Hisham al-Sayed lying in a hospital bed and connected to an oxygen machine.

"Hamas holds two mentally ill, sick and suffering civilians, in violation of all international laws and regulations," the Prime Minister's Office said in a statement. "Distributing a video of a sick person is a heinous and desperate act."

"The State of Israel considers Hamas responsible for the health of the captured civilians.

"In addition, Hamas holds the bodies of two IDF soldiers, Hadar Goldin and Oron Shaul, also in violation of international law.

"Hisham al-Sayed is not a soldier, but a mentally ill Israeli citizen who crossed the border into the Gaza Strip several times before.

"Hamas is delaying any chance of a deal. Hamas' actions are proof that this is a cynical and criminal terrorist organization.

"The State of Israel will continue its efforts to return prisoners and missing persons at all times with responsibility and determination," the prime minister's statement concluded.

Defense Minister Benny Gantz also responded to the Hamas video, saying: “The video published by the Hamas terrorist organization, whose credibility is in question, is intended for extortion."

"In addition to holding the bodies of two fallen soldiers, Hamas is also holding hostage two innocent civilians. Hamas is paying and will continue to pay a price for its terrorist activities. The State of Israel will continue taking a variety of measures, until all our boys return home,” Gantz said.

Foreign Minister Yair Lapid said: "Israel views Hamas as directly responsible for the well-being of the Israeli civilians it is holding against international law. These are two mentally challenged individuals whose yearslong captivity is both cruel and unfathomable. Hamas is also holding the bodies of two IDF soldiers, Hadar Goldin and Oron Shaul z”l, trampling on both basic morality and international law."

"Hamas’s activities are proof that it is a vile terrorist organization which is holding hostage the people of Gaza, who are paying the price for its actions.

"I call on the international community, including the World Health Organization, the International Red Cross, and organizations working with the mentally challenged, to condemn Hamas for its inhumane behavior and to demand it act according to international law and free the civilians and bodies it is holding.

"The State of Israel will continue to undertake every effort to bring home IDF soldiers and Israeli civilians being held captive by Hamas,” Lapid said.

Hamas released the video a day after its military wing issued an unusual statement on the condition of the Israeli citizens it holds captive, claiming that the medical condition of one them has deteriorated.

Al-Sayed, a Bedouin citizen of Israel, has been held by Hamas since he wandered into Gaza in 2015. Hamas has also held another Israeli citizen, Avera Mengistu, since 2014. Both men suffer from mental illness.

Hamas has also been holding the bodies of IDF soldiers Hadar Goldin and Oron Shaul since Operation Protective Edge in 2014.

Hamas has attempted to create the impression that Goldin and Shaul are still alive in order to secure a more favorable prisoner exchange with Israel. A recent article in the Hamas-run newspaper 'Palestine' claimed that Shaul was bound to a wheelchair and that Goldin was in good health.

An Israeli security source said in response that there Israel has no information about a change in the health of the prisoners held by Hamas. He added that this appeared to be an attempted psychological warfare by the terrorist organization
