Petraeus scandal engulfs general

The sex scandal that led to the resignation of CIA director David Petraeus has widened, with the top US commander in Afghanistan under investigation for alleged “inappropriate communications” with a woman who is said to have received threatening emails from General Petraeus’ former lover.

Defence Secretary Leon Panetta revealed that the Pentagon had begun an internal investigation into thousands of pages of emails from General John Allen to a second woman involved in the Petraeus case.
