The United Nations is demanding an investigation into how the Israeli military killed one of its Palestinian schoolteachers by blasting open the front door of her Gaza home with explosives in the presence of three of her children. Thirty-four-year-old Wafer Shaker al Daghma was killed last week as she stood preparing to open the door of her home to the Israeli troops. She was a teacher at a local UN Relief and Works Agency elementary school. Meanwhile, hundreds of thousands of Gazans are without power today after Gaza officials were forced to shut down the region’s only power plant because Israel hadn’t provided enough diesel to run the plant.
