The US created a text-message social network designed to foment unrest in Cuba, according to an investigation by the Associated Press news agency.

ZunZuneo, dubbed a "Cuban Twitter", had 40,000 subscribers at its height in a country with limited web access.

The project reportedly lasted from 2009-12 when the grant money ran out.
