Israel's Ambassador to the United Nations Gilad Erdan on Tuesday delivered remarks in the UN Security Council in which he strongly criticized the Council for ignoring the issue of Israeli captives held by the Hamas terror group in the Gaza Strip.

"Despite the heinous actions of Hamas, this council remains silent," Ambassador Erdan said. "Hamas is undoubtedly one of the most critical barriers to any advancement between Israelis and Palestinians, but it seems from the UN reports that this murderous terror group does not even exist."

In a video presented to the Security Council, Sha'aban a-Sayed, the father of Israeli-Muslim Hisham a-Sayed, who has been held in cruel captivity by Hamas for seven years, said, "For seven years, Hamas has been playing with our hearts. My son Hisham has special needs and suffers from mental and intellectual disabilities. I ask for the Security Council to intervene and work for his release. (Hamas) is holding him as a bargaining chip."

Hamas last month released a video purportedly showing al-Sayed in a hospital bed and hooked up to an oxygen machine.

The video was published a day after the military wing of Hamas 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.
