The Hamas militant group has claimed it intended to release two more hostages for "humanitarian reasons" but Israel "declined to receive them".
Abu Ubaida, spokesman for the Izz el-Deen al-Qassam Brigades, said in a statement said it informed Qatar yesterday of its intentions.
He did not explain why Israeli allegedly refused the captives, and there was no immediate response from Israel.
Qatar brokered talks which led to the release of US hostages Judith Raanan and her daughter Natalie Raanan yesterday.
Hamas said they too were freed for "humanitarian reasons".
