In the Gaza Strip, Israeli troops opened fire on Palestinian protesters Wednesday with live ammunition and chemical agents, injuring at least 65 people. The protesters were marking the 71st anniversary of the Nakba, or Catastrophe, when hundreds of thousands of Palestinians were forcibly expelled from their homes after the state of Israel was formed. One protester was left in serious condition, with 16 injured by gunfire. Others were treated for gas inhalation from tear gas and skunk spray, a chemical concoction that smells like corpses and feces.
