The United Nations is reducing its presence in Gaza by withdrawing about one-third of its international workers following repeated strikes by Israel. This decision comes at a time when humanitarian needs are increasing and Israeli attacks are killing hundreds of Palestinians. The U.N. will retain a presence in Gaza to continue providing aid to civilians. At least 280 U.N. staff members have been killed in Gaza since the start of the war. Israel has blocked all humanitarian aid into Gaza since March 2, leaving two million people without essential supplies.
