Israeli forces make a lethal strike on a U.N. aid warehouse in Rafah.

The Israeli military confirmed that it had bombed an aid warehouse in Rafah in southern Gaza on Wednesday, saying it had “precisely targeted” and killed a Hamas commander in an attack that the United Nations said also killed at least one aid worker and injured 22 others.

The Israeli military said the Hamas commander, whom it identified as Muhammad Abu Hasna, was “involved in taking control of humanitarian aid” and coordinating “the activities of various Hamas units.”

UNRWA, the U.N. agency that supports Palestinians, said the strike in Gaza’s southernmost city hit one of its facilities that serves as both an aid warehouse and a food distribution center.

The agency, formally the United Nations Relief and Works Agency, is the largest provider of aid on the ground in Gaza and the chief lifeline for the enclave’s 2.2 million residents, more than half of whom have been forced by Israeli military orders or fighting to cram into Rafah.

The UNRWA facility was not distributing food to civilians on Wednesday, but more than 50 staff members were working at the facility when it was hit by Israeli forces around noon, according to Juliette Touma, an UNRWA spokeswoman. Physical damage to the facility appeared to be minimal, but the human toll was “quite high” and some of the 22 wounded aid workers were “severely injured,” she said.
