In what may be the sickest “joke” of the weekend, NBC News’s official Twitter has been hacked. The last two tweets are reporting terrorist attacks and the account is not yet back in the network’s control:

“Breaking News! Ground Zero has just been attacked. Flight 5736 has crashed into the site, suspected hijacking. more as the story develops.”

“Flight 4782 is not responding, suspected hijacking. One plane just hit Ground Zero site at 5:47. #groundzeroattacked”
