More than one border crossing is needed to deliver aid to the besieged Gaza Strip and Kerem Shalom controlled by Israel is the only one equipped to take enough trucks, the United Nations has said.

“More than one entry point into Gaza is indispensable if we are to make a difference. Kerem Shalom, between Israel and Gaza, is the only crossing equipped to rapidly process a sufficiently large number of trucks,” senior UN aid official Lisa Doughten told the UN Security Council.

According to Reuters, Doughten was speaking on behalf of UN aid chief Martin Griffiths, who is in Israel working to increase deliveries.

US Ambassador to the United Nations, Linda Thomas-Greenfield, said the number of trucks entering Gaza “must be scaled up urgently.” The United States has been trying to balance staunch support for its ally Israel with growing global concern about the humanitarian crisis.
