United Nations aid chief Tom Fletcher said Israel cleared nine trucks of aid on Monday to enter Gaza through the Keren Shalom crossing following 11 weeks of a complete blockade.
"But it is a drop in the ocean of what is urgently needed, and significantly more aid must be allowed into Gaza, starting tomorrow morning," Fletcher said in a statement.
"To reduce looting, there must be a regular flow of aid, and humanitarians must be permitted to use multiple routes. Commercial goods should complement the humanitarian response," he said.
