The Ministry of Health in Gaza said on Monday that the four-year-old child died as a result of failure in hospital back-up generators, a Press TV correspondent reported.
On Friday, an infant also died in the coastal enclave after the generator powering his respirator ran out of fuel.
The Israeli blockade of Gaza has inflicted many sufferings, including fuel shortages on Palestinians.
Gaza has been relying on fuel imported from Egypt, but Cairo has recently cut off the supplies, causing 18-hour-a-day power cuts. Prolonged power outages caused by shortage of fuel continue to take their toll on hospital patients in the Gaza Strip.
Last week, thousands of people staged a protest in the Gaza Strip and called on Egypt to resume the flow of fuel to the besieged territory.
