UN Secretary-General Antonio Guterres on Friday visited the Egyptian side of the Rafah border crossing with Gaza to urge progress on the humanitarian mission to deliver aid to the besieged Palestinian territory.

Cargo planes and trucks have been bringing food, medicine and other aid to the Rafah crossing with Egypt, but to date no aid deliveries have started.

Guterres has called for conditions to be met in order for deliveries to begin entering Gaza.

"We are actively engaging with all the parties, with Egypt, Israel, the United States... in order to have these trucks moving as soon as possible," Guterres told journalists.

Israel cut off the Gaza Strip and began bombardments of Hamas targets after the militant group launched a terror attack on southern Israel on October 7, in which at least 1,400 people were killed, according to Israel's military. The Hamas-run Gaza Health Ministry said on Thursday that 4,137 Palestinians have been killed and over 13,000 wounded.

The UN and humanitarian organizations say food, drinking water, and medical supplies are desperately needed in Gaza.
