CAIRO/PARIS (Reuters) - No new radio signal has been received from an EgyptAir jet since the day it crashed in the Mediterranean last week, sources close to the investigation said on Friday. A radio signal picked up on the day of the crash from the plane's emergency locator transmitter (ELT) allowed officials to determine a broadly defined search zone, but nothing new has since been detected, the sources told Reuters. "There has been nothing since day one," a source familiar with the investigation said.
