The United States on Saturday welcomed the arrival of aid trucks from Egypt in the war-torn Gaza Strip, and urged all parties to keep the Rafah crossing open.
US Secretary of State Antony Blinken urged "all parties to keep the Rafah crossing open to enable the continued movement of aid that is imperative to the welfare of the people of Gaza", according to a statement.
AFP journalists on Saturday saw 20 trucks from the Egyptian Red Crescent, which is responsible for delivering aid from various UN agencies, pass through the Rafah border crossing from Egypt into Gaza.
"We have been clear: Hamas must not interfere with the provision of this life-saving assistance," Blinken said.
The opening of the supply route came after days of intense negotiations and an agreement reached by US President Joe Biden with Israeli Prime Minister Benjamin Netanyahu and Egyptian President Abdel Fattah Al-Sisi during Biden's visit to Israel earlier this week.
Saturday's was the first such delivery since the war broke out two weeks ago between Israel and Hamas, which rules the Palestinian enclave of 2.4 million people.
On 7 October, Hamas militants stormed into Israel from Gaza and killed at least 1,400 people. Since then, more than 4,100 Palestinians have been killed in Israeli bombardments, 70 percent of them women and children.
The US has offered Israel "unlimited" military support in its fierce and indiscriminate campaign against the Gaza Strip.
