The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) said 339 aid trucks had entered the Gaza Strip on Friday.
OCHA cited information from Israeli authorities and the guarantors of the ceasefire agreement – the United States, Egypt and Qatar.
The ceasefire agreement came into effect on Sunday morning. It is the first of three phases planned for a final ceasefire.
Immediately after the ceasefire began, humanitarian aid began to arrive in Gaza, where hundreds of thousands of people are currently homeless and have been facing a humanitarian catastrophe for months.
