Israeli air strikes in Gaza killed four children on Thursday, medics said, after a humanitarian lull in a 10-day conflict that has killed 237 Palestinians.
One strike hit the Sabra neighbourhood of central Gaza, killing three children -- Jihad, Waseem and Fulla -- from the Shuheiber family, emergency services spokesman Ashraf al-Qudra told AFP.
Their deaths were the first to follow the end of a five-hour humanitarian ceasefire, which brought some respite for residents of the besieged Palestinian territory.
Another strike shortly afterwards in the southern city of Khan Yunis killed four-year-old girl Rahaf al-Jubur, and a 29-year-old man, Hamza al-Abadleh.
Before the ceasefire took effect at 10:00 (0700 GMT), Israeli tank fire killed three men in their twenties in the southern city of Rafah, Qudra said.
One Israeli has also been killed by rockets fired by Palestinian militants.
The Rafah deaths came after another seven Palestinians were killed overnight.

Two men were killed in Gaza City, another two in Deir al-Balah and a fifth in northern Beit Lahiya.
One man was also killed in southern Khan Yunis and another in Rafah, Qudra said.
In addition, 1,690 people had been injured during the conflict, Qudra said.
Israel and the Hamas movement announced Thursday they were observing a five-hour humanitarian truce requested by the United Nations.
According to figures provided by the Gaza-based Palestinian Centre for Human Rights (PCHR), more than 80 percent of those killed have been civilians.
The only Israeli fatality has been a civilian killed on Tuesday evening when a projectile exploded near the Erez crossing between Gaza and southern Israel, medics said.
At least four Israelis have been seriously wounded.
Since the latest violence began before dawn on July 8, at least 1,048 rockets fired from Gaza have struck Israel, and another 282 have been shot down by the Iron Dome air defence system, army figures show.
In its air war aimed at halting the rocket fire, Israel has struck more than 1,750 "terror targets" across the coastal enclave, the army said.
