The proposal announced by Hamas to release an American-Israeli hostage and four bodies of dual nationals is based on discussions with US envoy Adam Boehler, according to a senior Arab diplomat. The four bodies are believed to be the remaining American-Israeli hostages. In exchange, Hamas is demanding the release of Palestinian prisoners, aid delivery to Gaza, and Israeli commitment to enter talks for the second phase of the deal. Hamas is willing to negotiate the identities of the Palestinian prisoners to be released once Israel agrees in principle to the deal. Both the US and Israel have rejected Hamas's offer.
