An Israeli security official has announced that the delivery of humanitarian aid to the Gaza Strip has been suspended “until further notice,” following a deadly attack on Israeli soldiers earlier this morning that prompted Israel to launch a series of airstrikes, The Times of Israel reports.

The official, speaking on condition of anonymity pending an official announcement, said the suspension comes just over a week after the start of a U.S.-proposed ceasefire aimed at ending the two-year war.

At the same time, Axios cites a U.S. official who said that Israel informed Washington it will reopen the crossings for humanitarian aid on Tuesday morning, after Jerusalem had failed to notify the White House in advance of its decision to close them.

“Due to the intensity of the bombings and dozens of casualties among Hamas militants, Israel today halted the movement of aid trucks. Deliveries will resume once the airstrikes end,” an Israeli official said.

Another source told Kan News that “under U.S. pressure,” Israel’s political leadership has ordered that humanitarian aid deliveries to Gaza resume tomorrow, noting that “official directives on this matter have not yet been updated, but this is the new direction.”
