FRANKFURT (REUTERS) - The diplomatic spat between Turkey and the Netherlands spread online on Wednesday (March 15) 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 and also some regular Twitter users.

President Tayyip Erdogan has suspended high-level diplomatic ties with the Netherlands and branded the country's citizens"Nazi remnants" for preventing his ministers at the weekend from addressing rallies of Turks living there.

Hijacked accounts featured tweets with Nazi symbols, a variety of hashtags and the phrase "See you on April 16", an apparent reference to the date of Turkey's planned referendum to grant Erdogan more powers.

The Twitter accounts hijacked included those of the European Parliament and the personal profile of French politician Alain Juppe.

They also included the UK Department of Health and BBC North America, both of which subsequently appear to have recovered, along with the profile of Marcelo Claure, the chief executive of US telecoms operator Sprint Corp, which remains hijacked.

Other accounts included publishing sites for Reuters Japan, Die Welt and Forbes and several non-profit agencies including Amnesty International and Unicef USA as well as Duke University.

The Twitter profile of BBC North America noted: "Hi everyone - we temporarily lost control of this account, but normal service has resumed".
