“The current situation in Gaza is catastrophic and words can’t describe it,” MSF wrote on X, citing Loay Harb who is working in northern Gaza.
Harb said the group has no electricity, water, flour or internet connection, which has created instability for residents.
“We are going through very difficult times due to the siege, poverty, and starvation,” he added.
Harb is one of four remaining MSF staffers in Gaza City.
He said the medical situation of patients is very complex and there are not enough beds and spaces.
Israel has waged a deadly military offensive on the Gaza Strip since an Oct. 7 cross-border attack led by Hamas in which 1,163 people were killed.
More than 31,500 Palestinians, mostly women and children, have since been killed in Gaza, and 73,546 injured amid mass destruction and shortages of necessities.
The Israeli war has pushed 85% of Gaza’s population into internal displacement amid a crippling blockade of most food, clean water and medicine, while 60% of the enclave's infrastructure has been damaged or destroyed, according to the UN.

Israel is accused of genocide at the International Court of Justice. An interim ruling in January ordered Tel Aviv to ensure its forces do not commit acts of genocide, and guarantee that humanitarian assistance is provided to civilians in Gaza.
