A billboard truck drove near Harvard’s campus Wednesday displaying the names and photos of Harvard students whose organizations signed a statement blaming solely Israel for the deadly attacks by Hamas.

The “doxxing truck” appeared days after the Harvard Palestine Solidarity Groups, a coalition of Harvard student groups, earlier this week released a statement that held “the Israeli regime entirely responsible for all unfolding violence,” following the attacks by Hamas that have killed more than 1,200 Israelis and more than 25 American citizens. More than 1,400 in Gaza have also been killed since Israel started strikes on Gaza following the deadly Hamas attack.

Some students and their groups have since distanced themselves or withdrawn their endorsements from the statement amid an intense backlash inside and outside of Harvard. Several said they did not read the statement before they signed it.
