World Central Kitchen announced Sunday that it will resume operations in Gaza with a local group of Palestinian aid workers, nearly a month after seven members were killed in an Israeli attack on the organization’s convoy.

Israeli military officials described the attack as “serious mistake”, citing as the cause a series of failures, which related to problems in communication, but also to violations of the operational procedures of the army.

Washington-based World Central Kitchen still to call for an independent, international investigation into the April 1 attack while he maintains that he has received “no concrete assurance” that the operational procedures of the Israeli army have changed. But the “humanitarian situation in Gaza remains dire,” aid chief Erin Gore said.

“We are restarting our operation with the same energy, dignity and focus on feeding as many people as possible,” he said.

The aid group said it had distributed more than 43 million meals in Gaza so far and that its trucks waiting to enter the enclave via the Rafah crossing in the south are carrying nearly eight million meals. World Central Kitchen said it also plans to ship trucks to Gaza via Jordan and will open a kitchen in Al-Mawasi, a small coastal village that the Israeli military has designated a “humanitarian zone” safe for civilians, although the attacks there have continued.
