Joe Biden rebuked Israel on Friday, saying it had “no excuses” for not letting more aid into Gaza as he announced the US will soon begin airdropping food into the enclave.

Biden’s announcement and criticism come amid an increasingly acute humanitarian crisis on the ground after months of Israeli attacks in the enclave and is another sign of the US president’s deepening frustration with Israel’s Prime Minister Benjamin Netanyahu.

“We need to do more and the United States will do more and in the coming days, we are going to join with our friends from Jordan and others to provide airdrops of supplies,” Biden said, adding that the US was also exploring the possibility of opening “a marine corridor delivering large amounts of humanitarian assistance”.
