Israel ordered a “total siege” of the territory following the Hamas attack, which left about 1,400 dead, most of them civilians, according to Israeli authorities.
The World Health Organization warned Thursday that hospitals no longer have fuel for generators, and that about 1,000 people who need dialysis will also be at risk.
Trucks with humanitarian aid began trickling into the Strip from Egypt over the weekend. On Sunday, six tanker vehicles with fuel crossed.
Israel fears that the fuel will help Hamas, even though what little remains in Gaza is used for generators to keep medical equipment running.
The Gaza Health Ministry declared on Saturday that 130 premature babies were at risk of dying due to lack of fuel.
Some 160 women give birth every day in Gaza according to the UN Population Fund, which estimates that there are 50,000 pregnant women in the territory of 2.4 million inhabitants.
Although Israel claims it is targeting Hamas, children account for a huge proportion of the more than 4,600 deaths recorded by the Islamist movement’s health ministry.
Entire families, including pregnant women, have died in the attacks, and every day parents are seen carrying the bodies of their children in white shrouds down the street.
Doctors at Najjar Hospital in Rafah recounted on Thursday how they had tried in vain to save the fetus of a woman who died in an airstrike on her home.
