Israeli troops killed three Palestinians wanted in connection with a deadly attack against Israelis, the Israeli military said on Thursday, the latest bloodshed in a relentless wave of violence.The military said the men were behind an attack last month on a car near a Jewish West Bank settlement that killed a British-Israeli mother and two of her daughters. The military said it entered the heart of the flashpoint city of Nablus in the occupied West Bank early on Thursday, and in a fierce gunbattle killed three suspects, two of whom it alleged were militants affiliated with Hamas. It identified the men as Hassan Katnani, Moaz Masri and Ibrahim Hura.
