Unicef’s executive director, Catherine Russell, has released a statement condemning a “deadly weekend of attacks in North Gaza”, saying more than 50 children have been killed in the Jabalia area over “the past 48 hours alone”, Al Jazeera reports.

Russell added that she had also received reports that a Unicef staffer working on the polio vaccination campaign was attacked on Saturday by a suspected Israeli quadcopter in Jabalia.

“This morning, the personal vehicle of a Unicef staff member working on the polio vaccination campaign came under fire by what we believe to be a quadcopter while driving through Jabalia — Elnazla. The car was damaged. Fortunately, the staff member was not injured. But she has been left deeply shaken,” she said.

“The attacks on Jabalia, the vaccination clinic and the Unicef staff member are yet further examples of the grave consequences of the indiscriminate strikes on civilians in the Gaza strip,” Russell added.
