An Israeli navy boat fired toward a Palestinian fishing vessel off Gaza on Saturday in a first Israeli violation of a week-old truce in Gaza, Palestinian security officials said. The vessel caught fire, but no one was hurt, the security officials said. The Associated Press quoted Israeli military as saying it was unaware of such an incident. Also in Gaza, an 11-year-old boy died of injuries he sustained two weeks earlier in an Israeli military operation in the northern Gaza town of Beit Lahiya, hospital doctors said. The boy died Saturday at Gaza City's Shifa Hospital.
