The Israel Defense Forces and the Coordination of Government Activities in the Territories agency announced Tuesday the opening of a new humanitarian aid crossing into the Gaza Strip, on the same day a U.S. deadline to improve the flow of aid expired.
"In accordance with directives from the political echelon, and as part of the effort and commitment to increase the volume and routes of aid to the Gaza Strip, the 'Kisufim' crossing was opened" for "the transfer of humanitarian aid trucks," the statement said.
The deliveries will include "food, water, medical supplies and shelter equipment to central and southern Gaza," the statement said. The supplies underwent "strict security checks at the Kerem Shalom crossing" before being sent into the strip, the IDF and COGAT said.
An Oct. 13 letter signed by Secretary of State Antony Blinken and Defense Secretary Lloyd Austin warned that continued failure to allow adequate aid into Gaza may trigger U.S. laws restricting military support for Israel.
Among the letter's demands were that Israel allow a minimum of 350 truckloads of goods to enter Gaza each day, that it open a fifth crossing into the besieged territory, that it allow people in Israeli-imposed coastal tent camps to move inland before the winter and that it ensure access for aid groups to hard-hit northern Gaza.
The letter also called on Israel to halt legislation -- since passed -- that would hinder the operations of the U.N. agency for Palestinian refugees, known as UNRWA.
