Posting on X on Wednesday, he wrote that a WHO-led convoy encountered two Israeli tanks while on the way back from a mission last Saturday. Shots were fired from the tanks near the convoy, he said, adding that the convoy had received clearance.

Nobody was hurt during the incident, he said. "This is unacceptable," he said, noting that humanitarian workers in Gaza deliver critical aid "amid extreme danger and life-threatening conditions". He added: "The minimum they deserve for their service is safety.

Shots were fired from the tanks near the convoy.
