Twitter accounts hacked by 'Turkish government supporters'

Twitter accounts, including that of Amnesty International, have been hacked by a group claiming to support the Turkish government.

The tweets, which began with a swastika, linked to a YouTube video entitled: "Nazi Germany, Nazi Holland, see you April 16" (the date of a constitutional referendum in Turkey).

Other accounts hacked included ones belonging to Unicef USA, the Atlanta Police Department, French politician Alain Juppe, the UK's Department of Health, Die Welt, Forbes and Central Bedfordshire Council.

The European Parliament was also affected, tweeting: "Good morning. We briefly lost control of this account earlier, but everything is now back to normal."

A Twitter spokesperson said they had "quickly located the source which was limited to third party app. We removed its permissions immediately. No additional accounts are impacted."

It comes as people in the Netherlands vote in a parliamentary election.

The final days of campaigning were overshadowed by a diplomatic crisis between the Dutch and Turkish governments.

Over the weekend, police used water cannon, horses and dogs to break up the pro-Turkey demonstration attended by hundreds as some activists threw bottles and stones.

The protest came after two Turkish ministers were stopped from campaigning in the Netherlands in favour of giving Turkish President Recep Tayyip Erdogan more powers in the forthcoming referendum.

In response, Mr Erdogan has suspended diplomatic talks with the Netherlands and described the country's citizens as "Nazi remnants".
