Shortly after key aid wheeled into the besieged Gaza, an explosion and the sound of ambulances were heard near the Rafah crossing between Egypt and the Gaza Strip, Reuters reported.
However, the news outlet could not verify the cause and the exact location of the blast.
17 trucks carrying a second lot of aid in the last two days were allowed to enter the war-torn Gaza strip.
Palestinians have been under massive bombing ever since a conflict between Hamas and Israel broke out on October 7.
