All four hostages are female Israeli soldiers. They are expected to be released Saturday in accordance with a ceasefire agreement with Israel that's halted fighting in the Gaza war since last weekend.

Prime Minister Benjamin Netanyahu said on Friday that Hamas has violated an agreement on the release of hostages with its publication of those to be released on Saturday.

Hamas named four Israeli women soldiers it plans to release from captivity in a second hostage-for-prisoner swap, as the Gaza ceasefire nears the end of its first week.
