Hackers tweet false plane attack reports
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 on the site.
The network called yesterday's hacking "reckless and irresponsible". It says it's working with Twitter to fix the problem.
Tomorrow is the 10th anniversary of the terror attacks of September 11, 2001, when hijacked planes crashed into the twin towers.
