Ten-year-old child killed in Gaza City, while three others died following a drone strike in Khan Younis.
Israel has hit the Gaza Strip with missiles and artillery for the first time in three days, while Palestinian fighters launched a barrage of rockets at Israel, just hours after a ceasefire between the two sides expired.
An Israeli air strike killed a 10-year-old child in Gaza City, the first death reported since a 72-hour truce expired at 8am (05:00 GMT), while three others were killed in a drone strike in the Khan Younis district, Palestinian medics said on Friday. The number of injured in the last 10 hours were also up from six to 22.
The Israeli army said that as of Friday afternoon, more than 45 rockets were fired into southern Israel after the truce ended. Three of the rockets were intercepted by the Iron Dome missile defence system. Two Israelis were wounded, the army said.
