Hamas has signaled its readiness to negotiate the second phase of the ceasefire in Gaza, warning that any attempt to pull back from the truce will lead to more suffering for the captives and their families. The group issued a statement after a swap in which it handed over what it said were the remains of four hostages in exchange for the release of over 600 Palestinian prisoners held by Israel. Negotiations for the second phase, in which Hamas would release dozens of remaining hostages in exchange for more prisoners and a lasting ceasefire, have not yet begun.
