Israel Defense Forces (IDF) bombed a UN school-turned-evacuation center in Al-Shati refugee camp, near Gaza City, as they carried out an intense series of bombardments on Friday. Palestinian officials have reported that three Palestinians were killed and 15 were injured.

The military boasted of the attack on social media, saying it struck a shipping container in the school grounds and attaching a picture of the container with a large UN logo visible on the adjacent building. The IDF claimed that it was targeting Hamas militants, an unverified claim that Israel has parroted many times in accounting for its countless bloody airstrikes over the past months.

This is the second time that Israel has struck a UN Relief and Works Agency for Palestine Refugees (UNRWA) school over the course of 48 hours. On Thursday, Israeli forces deployed U.S.-made bombs in an attack that killed at least 40 Palestinians, including 14 children, in Nuseirat refugee camp.
