Celebrity chef José Andrés told Reuters news agency on Wednesday that the Israeli attack that killed seven of his food aid workers in the Gaza Strip was aimed at them. “systematically, machine by machine.”

In a video interview, Andres said that the charity group he founded, World Central Kitchen (WCK), maintains clear communication with the Israeli army, which, according to the chef, He knew the movements of his employees.

It wasn’t “a bad luck situation where, oops, we dropped the bomb in the wrong place,” Andres said. “Even if we did not act in coordination with the (Israel Defense Forces), no democratic country and no army could attack civilians and humanitarian workers.”

The volunteers were killed by gunfire around them shortly after they were overseeing the unloading of 100 tons of food delivered to Gaza by sea. The Israeli army expressed “deep sadness” over the incident and Prime Minister Netanyahu called it forced.

Andres, 54, said there could have been more than three attacks on the aid convoy and explained that he was supposed to be in Gaza with his team, but for different reasons. “He couldn’t come back again” in place.

The chef, who spoke with US President Joe Biden on Tuesday, put pressure on Washington to do more to stop the war. “The United States must do more to tell Prime Minister Netanyahu that this war must end immediately,” he claimed.

He noted that his organization continues to study the security situation in the Gaza Strip, while simultaneously considering the possibility of resuming humanitarian aid supplies.

Australian, British and American citizens were among seven World Central Kitchen aid workers killed when their convoy was attacked shortly afterwards. They will supervise the unloading of 100 tons of food delivered to Gaza by sea.

The aid convoy was damaged as it left a warehouse in Deir al-Balah, the aid group said. At least 196 aid workers have been killed in the Gaza Strip since October. Hamas has previously blamed Israel for attacks on humanitarian aid distribution sites, according to the UN.

World Central Kitchen last month began delivering food aid to starving populations in the northern Gaza Strip via a shipping corridor from Cyprus in partnership with Spanish charity Open Arms, coordinating closely with the Israeli military, Arab countries and others, Andres previously said.
