VIDEO: First of 20 aid trucks enter besieged Gaza from Egypt

The first of 20 trucks carrying humanitarian aid entered the war-torn and besieged Gaza Strip on Saturday through the Rafah border crossing with Egypt, said the media correspondents on both sides.

UN humanitarian chief Martin Griffiths said he was "confident that this delivery will be the start of a sustainable effort to provide essential supplies... to the people of Gaza" and warned that "this first convoy must not be the last".

The border crossing was closed again after the passage of the trucks from the Egyptian Red Crescent, which is responsible for delivering aid from various UN agencies.

It was the first such delivery since the war broke out more than two weeks ago between Israel and Hamas.

Rafah is the only route into Gaza that is not controlled by Israel, which agreed to allow the aid in from Egypt following a request from its top ally the United States.
