Hackers send terror alerts from NBC's Twitter
New York - NBC says hackers briefly took over the NBC News Twitter feed and sent out false reports of a plane attack on the World Trade Centre site.
The network calls Friday's hacking "reckless and irresponsible". It says it's working with Twitter to fix the problem.
Sunday is the 10th anniversary of the terror attacks of September 11 2001, when hijacked planes crashed into and destroyed the twin towers.
