Palestinian radio says Israeli artillery fire killed an eight-year-old girl when the shell hit her home in the northern Gaza Strip. Thirteen other children in the house were reported to be wounded.
Witnesses said an artillery round set the house in Beit Lahiya on fire. A relative said all the casualties were members of the same family.
The Israeli military has not commented on the death, but confirmed that Israel has been shelling sites that it suspects Palestinian militants are using to fire rockets into southern Israel.
At least 16 Palestinians have been killed since last Friday, when Israel began stepping up air and artillery strikes in Gaza, in a push to curb the rocket fire.
