The Director of the World Health Organization, Tedros Ghebreyesus, warned on Sunday that the situation in the health sector in Gaza was “unimaginable,” and stressed that reports of violent Israeli bombing “stimulate horror.”

Ghebreyesus said, in a tweet on the “X” platform, that “reports about the ongoing hostilities and violent bombing in Gaza raise terror.”

He added: "Yesterday (Saturday), our team visited Nassar Medical Hospital in the south (Gaza Strip). It was crowded with 1,000 patients, that is, 3 times its capacity."

He continued: "(The hospital) had countless people searching for shelter in every corner... Patients were receiving care on the floor, screaming in pain."

He stressed that "these conditions are completely inappropriate and unimaginable in the field of providing health care."

Ghebreyesus concluded by saying: "I cannot find strong enough words to express our concern about what we are witnessing," reiterating the call for a "ceasefire now."

On December 1, a humanitarian truce between the Palestinian resistance factions and Israel ended, concluded with Qatari-Egyptian mediation and lasted for 7 days, during which prisoners were exchanged and limited humanitarian aid was brought into the sector, which is inhabited by about 2.3 million Palestinians.

Since the end of the truce, the Israeli army has attacked more than 400 targets throughout Gaza during the last 24 hours, according to a statement on Saturday. As a result, nearly 200 Palestinians were killed, bringing the death toll as of Saturday afternoon to 15,207, while the number of wounded rose to 40,650, according to the government media office in Gaza.

Since October 7, the Israeli army has been waging a devastating war on Gaza, which has left massive infrastructure destruction and an “unprecedented humanitarian catastrophe,” according to official Palestinian and UN sources.
