Napolitano: US terror threat highest since 9/11
The threat of terrorism against the US homeland is in some aspects "at its most heightened state" since the 9/11 attacks, US Homeland Security Secretary Janet Napolitano has told members of Congress.
The US faced new threats by groups already inside the country, inspired by al-Qaeda, she said.
At least 63 US citizens have been charged or convicted of terrorist acts or related crimes since 2009, whilst home-grown plots have reached their highest level since 11 September 2001, according to the National Counterterrorism Centre.
