On-air gaffes, runaway autocues and strapline spelling mistakes are a dime a dozen on TV but possibly one of the worst typos in recent news broadcasting history comes in the form of a latest CNN report.

During a live news broadcast, the network ran a strapline – a key emboldened headline that runs across the TV screen under the presenter- citing that a 'Seal who claims he killed Obama under attack.'

However, it was on screen for less than a minute before it was corrected.

The writer was meant to write Osama bin Laden, in relation to the news story that the US Navy seal, who claims he killed the infamous terrorist group Al Qaeda leader, is under attack for his version of events.
