U.N. experts said in a report on Tuesday that Israel committed the crime against humanity of "extermination" by killing civilians sheltering in schools and religious sites in Gaza, part of a "concerted campaign to obliterate Palestinian life.

The Israeli military said it fired warning shots at people it referred to as suspects who it said had advanced toward its troops hundreds of yards from the aid site prior to its opening hours.

Palestinians say Israeli forces and allied local gunmen fired toward a crowd heading to an Israeli- and U.S.-supported food distribution center in the Gaza Strip
