The diplomatic spat between Turkey and the Netherlands spread online on Wednesday when a large number of Twitter accounts, many with no apparent connection to the dispute, were hijacked and replaced with anti-Nazi messages in Turkish.

The attacks, which appeared to be simply a form of political vandalism and used the hashtags #Nazialmanya or #Nazihollanda, took over accounts of high-profile CEOs, publishers, government agencies, politicians and also some regular Twitter users.
