UN humanitarian chief Tom Fletcher welcomed the move, but said Israeli authorities were only allowing in limited aid after 11 weeks of completely blockading the war-torn enclave.
"Today, nine of our trucks were cleared to enter, via the Kerem Shalom crossing," he said in a statement.
"Given ongoing bombardment and acute hunger levels, the risks of looting and insecurity are significant," he added.
"The limited quantities of aid now being allowed into Gaza are of course no substitute for unimpeded access to civilians in such dire need."
Israel on Monday said five aid trucks had so far entered Gaza.
