Palestinians have accused Israel of breaking its own ceasefire by launching an attack which killed an 8-year-old girl and left 29 people wounded in a Gaza refugee camp.
Gaza Health Ministry spokesman Ashraf Al-Qidra said the strike on a house in the Shati camp, in Gaza City took place after the truce was scheduled to start this morning.
An Israeli military spokeswoman said she was checking the report.
There have been two days of quiet in Gaza. No rockets or missiles, no more destroyed houses, no more ambulance sirens screaming.
A three-year-old girl has been rescued from Gaza and brought to London for life-saving heart surgery.
A small team of NHS doctors and surgeons is travel to Gaza to set up facilities and establish how best to use specialists and equipment.
