The hashtags #Nazialmanya and #Nazihollanda (translated as Nazi Germany and Nazi Holland), were posted on several high profile accounts, including European Parliament, BBC North America, and Forbes, Reuters reported. The hijackings also included references to April 16, when Turkey is holding a referendum to give more power to President Recep Tayyip Erdoğan.
Some tweets also included a link to a pro-Erdogan YouTube video, and had background images replaced with a Turkish flag, the Verge reports.
According to Reuters, Twitter is investigating the hack.
The references to #Nazihollanda comes after Turkey imposed sanctions on the Netherlands and suspended high level political discussions after the country refused to let Turkish ministers campaign over the weekend. The Netherlands is holding national elections today.
