Hamas, a group that wants the land of Palestine, needs a new leader after Yahya Sinwar was killed by Israel.
One strong candidate is Khalil al-Hayya, a top Hamas official who has been involved in peace talks with Israel.
Sinwar was very important to Hamas, and his death comes just a few months after another leader, Ismail Haniyeh, was killed.
Even after losing Sinwar, Hamas continues to demand a ceasefire that includes Israel leaving Gaza and releasing the people they are holding hostage.
