The Islamic group Hamas says it will release hostages on Saturday in accordance with a ceasefire agreement with Israel.

Hamas made the announcement in a statement on Thursday after its delegation had visited Egypt for talks.

The statement says mediators in Egypt and Qatar confirmed that they would follow up on aid deliveries to the Gaza Strip "to remove obstacles."

Hamas announced a delay to the hostage release on Monday, accusing Israel of violating the ceasefire deal. It said Israel was not fully allowing relief supplies into Gaza, including mobile homes for displaced people and heavy machinery to clear debris. It also said Israeli forces were attacking residents in the enclave.

An Israeli government spokesperson said on Thursday that the ceasefire will end unless Hamas releases three living hostages on Saturday.
