The violence is one of the worst since the 11-day Israel-Hamas conflict in May. A 13-year-old Palestinian boy and an Israeli Border Police solider were among those critically injured.
Hamas militants launched incendiary balloons into Israel for a third straight day, prompting the Israeli response. A cease-fire after last month's 11-day conflict now appears in tatters.
In Gaza, a week since the ceasefire between Hamas and Israel was announced, many residents come out to enjoy the beaches. The truce ended 11 days of devastating Israeli bombardment of Gaza, killing 248 Palestianians, and rockets and other fire into Israel from the coastal strip that killed 12.
Delegations from Israel and Egypt meet in Cairo and Jerusalem to discuss establishing a permanent ceasefire between the Jewish state and Gaza's Hamas rulers. Egypt played a pivotal role in negotiating a ceasefire earlier this month between Israel and Gaza's Palestinian Islamist rulers Hamas, bringing an end to 11 days of deadly fighting.
Israel and Gaza have so far been keeping to an agreed cease-fire. The US is keen to shore up that arrangement with the visit of its secretary of state.
Inside a Gaza hospital, Mohammad al-Hadidi cradled his baby boy Omar -- his only surviving child after Israeli air strikes killed his wife and four other sons in the night. After the strikes, rescue workers pulled the five-month-old from the arms of his dead mother early Saturday, one of his tiny legs fractured in three places.
The World Health Organization (WHO) is asking for access to Gaza as the health care system in the Palestinian enclave is suffering critical shortages after days of heavy bombing.
Hamas said it expects a truce within days. German Foreign Minister Heiko Maas is also set to fly to Israel and Palestinian territories for talks over halting hostilities.
World leaders have urged a truce between Israel and Hamas but the UN Security Council has made no progress in issuing such a statement. The death toll in the fighting continues to rise.
The cease-fire is being monitored by Egypt. Israel and Hamas fought a 11-day war after escalating tensions in Jerusalem.
The idea of a two-state solution is almost as old as the conflict between Israelis and Palestinians. In light of the current hostilities, it also seems increasingly unrealistic.
South African President Cyril Ramaphosa tells FRANCE 24 that the situation in Gaza reminds him of the apartheid era in his own country, with Israeli actions against the Palestinians evocative of an apartheid state. He said South Africa stands by the Palestinians but urged both sides to sit down and negotiate as was done in South Africa in the early 1990s.
