The World Health Organization chief said on Thursday that 28 healthcare workers had been killed over the past 24 hours in Lebanon, where Israel has launched airstrikes.
"Many (other) health workers are not reporting to duty and fled the areas where they work due to bombardments," Director-General Tedros Adhanom Ghebreyesus told an online press briefing.
"This is severely limiting the provision of mass trauma management and continuity of health services," he said, Reuters reported.
The global health agency will not be able to deliver a large planned shipment of trauma and medical supplies to the country on Friday due to flight restrictions, he added.
