A Bedouin-Israeli father of a recently released hostage, who was held by Hamas for more than a decade, is demanding that the Arab world speak out against the terror group’s atrocities.

Shabaan a-Sayyid’s son Hisham, who has schizophrenia, crossed into the Strip in 2015. He was returned to Israel on Saturday in a near-catatonic state, and appeared to not recognize his own relatives.

Speaking to Hebrew-language media, a-Sayyid urged Arab countries to condemn Hamas, whom he said had acted contrary to Islam in their abusive treatment of his son.
