Two tweeters who passed on second-hand information about rumoured gun battles at schools in the city of Veracruz, face the possibility of up to 30 year’s jail time for terrorism and sabotage.

The two, a former teacher and a maths tutor, tweeted rumours they say they believed to be true, which caused as many as 25 car accidents as panicked parents rushed to fetch their children from schools where they believed gun battles was taking place.

There have been a number of gun battles in the city and nearby suburs, with drug traffickers having fired in a shopping area on one occasion and set off a grenade outside the aquarium in another.

So when the two tweeters heard rumours about firing and kidnappings at the schools they claim to have believed them and relayed them.

Human rights organisations have slammed the terrorism charges, saying the chaos is more a result of the ongoing drug wars in Mexico.
