The president and CEO of American Near East Refugee Aid (Anera) says the organisation has resumed operations in Gaza because the “needs were so great”, Al Jazeera reports.

Anera ceased operations in Gaza after the killings of the World Central Kitchen aid workers last week.

“We’ve worked hard over the past week, 10 days, to get some assurances, which we feel we have gotten for really the protection of aid workers and humanitarian work that should be there all the time in a conflict,” Sean Carroll told Al Jazeera.

He added that reports of a Unicef vehicle being targeted by an Israeli attack triggered more concerns over whether it was safe to return to Gaza.

“The truth is, it’s not really safe to go back to work, but our staff wants to,” he said.

“We do believe that there are new measures in place. We’ve been told that there will be no attacks on humanitarian missions or workers or in the area of a humanitarian operation.”
