Palestinian media say Israeli airstrikes in Rafah have killed 22 people. It comes as Israel's top military officer approved plans for a continuation of operations in the Gaza Strip.
The military said on Sunday that Israel Defense Forces Chief of the General Staff, Lieutenant General Herzi Halevi, endorsed the continuation. The move is believed to be part of preparations for a ground offensive into Rafah in the enclave's south.
Rafah is currently home to about 1.2 million people, including evacuees from other parts of Gaza.
Israel and Hamas have indirectly been engaged in negotiations for a pause in the fighting and the release of hostages held in Gaza.
Media outlets in the Middle East report a Hamas delegation will visit Egypt as early as Monday. They are likely to discuss a new proposal from Israel.
US news website Axios reports the proposal marks the first time Israel has suggested it's open to discussing an end to the conflict as part of a hostage deal.
Hamas has been demanding a ceasefire rather than a pause in fighting.
